Chain of Deals
"He traded sand for skins, skins for gold, gold for life. In the end, he traded life for sand."Character A needs something from character B, but character B wants A to get him/her something from character C, who wants something from character D, etc. etc. etc. In a comedy, the chain either collapses or is rendered moot at the end. One common way of this happening is that the item the character at the end of the chain received breaks or is otherwise unsatisfactory, and the character decides to take his original bartered-away item back. The next character decides that, if he doesn't get what he wants, he'll take his original item back as well, and so on and so forth all the way back up the chain. An alternative to this is that character Z wants what character A originally needed, thus closing character A off from the loop. In video games, this can be an extension ("extension" being the key word) of a Fetch Quest, as once you've fetched (or otherwise acquired) the first item, you just have to "fetch" the NPC's willing to trade for it. See also Fence Painting, Plot Coupon, Sidequest Sidestory, Linked List Clue Methodology and Match Maker Quest. Not to be confused with Chain of People.

She leaves the vegetables with a colleague of hers, receiving tickets to a play for helping her colleague to get her picky kids to eat vegetables. When trying to cash the ticket in, she's approached by men who want to buy the ticket off of her for a famous woman to view the play and the woman gives her a rare, limited edition bag.

Fairy Tales & Oral Tradition
- Older Than Print: The Japanese legend of the straw millionaire is this trope played completely straight. A poor peasant prays to the goddess of mercy for relief from his miserable life. She grants him a single piece of straw which he trades through his travels until fortunate circumstances lead to the hand in marriage of the daughter of a millionaire. One unique difference, however, is that the tale generally has most if not all trades actually consist of the peasant freely giving what he has to someone in need without expectations of payment, but receiving items as tokens of gratitude.
- There are two stories from The Brothers Grimm, both about a boy named Hans; in one, he trades all the way up to marrying a Princess; in the other, he trades all the way down to nothing (but is still happy, because the last thing he traded for was a freaking huge millstone that did nothing but weigh him down). This is deconstructed in a third Brothers Grimm story: Death of the Little Hen. The Hen starts choking on a nut, so her husband, the Rooster, rushes off to the well to get her some water. The well will only give him some water if he brings it a nearby bride's red silk shawl. The bride will only part with the shawl if the Rooster recovers her wreath, which is caught in a tree. By the time the Rooster completes the quests and makes it back to the Hen with the water, she's already choked to death.
- The Old Woman and the Pig, wherein the old woman implores a whole sequence to do something to the person before them to get the pig to jump over the stile. The last one does so, and the whole cascade ensues.
Old Woman: Cat, kill rat! Rat won't gnaw rope, rope won't hang butcher, butcher won't kill ox, ox won't drink water, water won't put out fire, fire won't burn stick, stick won't beat dog, dog won't bite pig, pig won't jump over the stile, and I shan't get home tonight!
- In a Russian fairy tale a rooster choked on a bean. His hen hurried to the housewife asking for some butter to lube rooster's throat, but the woman needed some milk from the cow, who needed the farmer to cut some grass for her, but the farmer needed a scythe from the blacksmith, so the hen ran to the smith, got a scythe and unwound the sequence. Naturally, cynical Russians spoofed the story, so when the hen reaches the blacksmith...
Hen: "Oh, good blacksmith, please give me a scythe. Our farmer will cut some grass for the cow, who will give milk, which the housewife shall churn into butter that I will lube rooster's throat with for he choked on a bean."
Blacksmith: "Why sure, I can give you a scythe, but wouldn't it be easier if you just ask me for some butter?"
Hen: "Yeah? And fuck up a cool quest?!"
- This is actually common enough in fairy tales to have its own Aarne-Thompson type number (550). The best-known variants are "Ivan Tsarevitch and the Grey Wolf" and "The Golden Bird", both of which follow the same pattern: The protagonist is tasked (by a wolf in the first story, a fox in the second) to steal a bird from a castle. He gets caught, but the king of the castle offers to give him the bird if he'll steal a horse from the second castle. He gets caught again, and sent to fetch a princess from a third castle in exchange for the horse. In the end, with the help of the wolf/fox, he manages to keep all three.
- A Scandinavian fairy tale about a man who bets someone that his wife loves him no matter what, and to prove it he has the other man listen by the door while he relates to his wife how he didn't take the cow to the market this morning, but traded it for a horse, which he then traded for a goat, and so on until he finally tells her that he traded a rooster for a meal since he was hungry, so essentially he gave the cow away with nothing to show for it.
- The Pirates of the Caribbean films tend to enjoy these types of deals and counter deals: in At World's End, Will Turner needs the Black Pearl to rescue his father, but Sao Feng promises it to Beckett; Beckett wants Jack Sparrow's compass, which Will eventually barters with Beckett, though Davy Jones' condition is the murder of Calypso; but the pirates want Calypso alive, and Barbossa wants her released, though Sao Feng thinks he's already captured her... while Jack swans through it all messing up everyone's chains looking for immortality... which he (sort of) had before the pirates came to rescue him because Barbossa needed — oh, you get the point.
- In the movie The Comrades of Summer the Russian baseball team needs a new backstop. One of the players steals the coaches Walkman and goes through a series of trades in this style. In the final trade he gets a new backstop and two new Walkmans.
- The American Astronaut has Sam, who must return the late king of Venus to his family in Earth, to do so, he must provide Venus with a new king; so he will give the owner of Jupiter a woman and he will give in return The Boy Who Saw A Breast so he can be the new Venusian king. The woman for the Jupiter ruler in turn, is a clon of Eddy, the owner of the Ceres Crossroads who wanted a cat
- Marcello Marcello turns this ad infinitum, considering it is supposed to be a Romantic Comedy.
- The 1980's children's novel "The Seventeenth Swap" is about a boy who wants to buy a special pair of boots for his crippled friend, but can't afford them. What he does have is a rare stamp that he trades to a stamp collector, and sixteen swaps later, he's able to get the boots.
- The Dragaera novel Orca follows this trope, as Vlad has to fulfill a series of deals in order to obtain a cure for a friend.
- Neil Gaiman and Dave McKean's children's book The Day I Swapped My Dad for Two Goldfish has the protagonist trade his father for two goldfish, then have to unravel the Chain of Deals that resulted afterwards to get his dad back.
- John tries such a chain in Me and My Little Brain after talking to a man who could start with a fifty-cent pocketknife and trade up to a twenty-dollar cow. He manages about nine or ten trades easily, but the chain collapses because he never considered what he would want out of the whole deal. He accepts a piglet as payment in the final trade, but since he can't keep it at home or afford to board it elsewhere, the other boy offers to take it back.
- In one of the Henry Reed books, Henry goes to visit an auction, and starting out with some fireplace tools that turn out to be valuable to another bidder who missed them, he parlays the two dollar bid on the tools through to another item and another, until he ends up getting an item and two dollars for his item, finally ending up with two items that the owner bid $40 apiece, a lot of money to Henry. By the time he's finished he's essentially traded things that he ends up getting something worth $100, which cost him nothing because he got the original $2 back during one of the trades.
- One Fine Day, an old children's book in which a fox gets his tail hacked off for trying to steal a woman's goods; in order to get it back he has to give her a sewing needle, leading to a chain of deals.
- There is a children's story about a woman who wants her son to go to school on time. He refuses, so she tells a cane to beat the boy up. The cane doesn't want to, so she tells a fire to burn the cane. When the fire refuses, she orders a puddle of water to put out the fire, then orders a cow to drink the water when refuses too, tells a butcher to kill the cow, orders a rope to hang the butcher, tells a mouse to gnaw on the rope, and finally tells a cat to eat the mouse, which it agrees to in return for a saucer of milk, and in the end the boy goes off to school. One has to wonder what the moral of the tale is, given that the sociopathic main character callously attempts to orchestrate the deaths of several people, animals and curiously sentient objects just because they refuse to carry out her murderous intents.
- This is how the Deveels in Aspirin's Myth Adventures series make their fortunes. The graphic novel even contains a visual representation of a chain of deals that begins with a coat hanger and concludes with a giant ruby.
- The Danish fairy tale writer Hans Christian Andersen also wrote a lot of short stories with all sorts of themes and messages — one of these is What Father Does is Always Right (guess the message here) about a man who goes to the market with a horse and makes a long chain of deals, each time lessening the value of his animal/ object and ending up with a sack of rotten apples. He meets a couple of rich Englishmen who make him a wager that his wife will be mad at him for it - however, when he gets home with them, it turns out that she's been insulted by a neighbor, and the rotten apples are just what she needs to get her revenge, and the Englishmen lose the bet.
- Example from a forgotten story in a magazine: The protagonist was named Scipio (after the Roman general) and he lived in a small town. His goal for the story required him to trade things with different people in succession with the end result of allowing a collector to complete his prized set of Napoleonic silver plates if the collector did what Scipio wanted him to do. This story of Scipio trading things to accomplish something apparently a regular feature in this magazine.
- In the Star Wars Expanded Universe, this is the species hat of the Squibs. The more complex and outrageous the deal, the more prestigious it is.

- Francis Spufford's Alternate History novel Red Plenty has a Soviet black marketeer whose entire business is built on these kind of arrangements.
- In one of the Jennings books, Jennings sends off for a sheet of free stamps from a catalogue, hands them round to his friends, and then discovers they were only free "on approval" and so has to get them back. Unfortunately, his friends have already traded them for numerous other possessions, which they can't demand back because those have been traded for other possessions, and so on.
- In Tai-Pan Dirk Struan and Jeff Cooper manage to set one up. Impressive since they are the only ones involved.
Cooper: ... and Venetian glass. Exquisite!Struan: Made in Birmingham. New method. I can sell you them for ten cents each.Cooper: Ten thousand at six cents each.Struan: Ten. Brock'll charge you twelve.Cooper: Fifteen thousand at seven cents each.Struan: Deal... if you promise to only import from Struan and place another order for at least thirty thousand within a year.Cooper: Deal... if you agree to take a shipment of cotton from Charleston to London on the return trip.Struan: How many tons?Cooper: Three hundred. Standard contract and payment.Struan: Deal... if you will act as a broker for us in this year's tea auctions, if we need one.
- In one Shel Silverstein poem, a boy trades a dollar his father gave him for two quarters, then three dimes, then four nickels, and finally five pennies. He thinks he made a great chain of deals because he has a bigger number of coins to count at the end, but his father knows better.
Live Action TV
- The M*A*S*H episodes "For Want of a Boot" and "The Price of Tomato Juice" both involve variations of this.
- By contrast, "The Long John Flap" features a series of separate exchanges involving a pair of Long Johns, but there's no chain to be unwound. Ditto "Give and Take", in which the unwanted assignment of soliciting charity donations gets passed around in this manner.
- In Star Trek: Deep Space Nine, this is the B-plots of the second-season episode "Progress," notable for containing the first mention of self-sealing stem bolts, and the fifth-season episode "In The Cards". In the seventh-season episode "Treachery, Faith, and the Great River", we learn that such chains are a tenet of Ferengi philosophy - the "Great Material Continuum".
Nog: There are millions upon millions of worlds in the universe, each one filled with too much of one thing, and not enough of another. And the Great Continuum flows through them all like a mighty river, from "have" to "want" and back again! And if we navigate the Continuum with skill and grace, our ship will be filled with everything our hearts desire!
- This example is one an unusual instance of this trope being played for laughs not ending in disaster, even though Nog using O'Brien's access codes puts the chief in serious danger of being arrested, court-martialed, or murdered by Martok at various points in the episode.
- Stargate SG-1 had one of these in the episode "The Ties that Bind"... which also featured Daniel Jackson as the Butt Monkey. Daniel and Vala needed to recover an item Vala stole from a former lover so he would reveal how to sever the bond left behind by the bracelets. Doing this involves a Chain of Deals with other people: the vendor she sold the item to wants the item he traded for it, an ex-smuggler at the monastery she sold that item to wants his old shuttle back, and the Lucian Alliance that has the shuttle isn't going to part with it so they have to steal it. Predictably, even when they finally get all the items back to their rightful owners, the bracelets' owner reveals that he doesn't know how to sever the connection but he thinks it will wear off...eventually.
- A short gag on Sports Night.
- Francis in Malcolm in the Middle attempts this to get something or other, and agrees to make exchanges between just about all the loggers in the camp. The problem for Francis is that it's a chain of promised deals, and he keeps making grander and grander promises to try to ground out the chain at something he can manage. He keeps going unsuccessfully until they find out it's rapidly becoming a complete sham and kick the crap out of him.
- An episode of Grey's Anatomy features a chain of kidney donations, where patient A's relative will donate to patient B, patient B's relative to patient C, etc. The chain almost falls apart at a number of occasions.
- Happens in an episode of Dark Angel as a side note rather than a plot point. Apparently this sort of thing is common given the setting.
- Rain attempts to pull one off in order to obtain hot concert tickets (Ron has backstage passes and wants a date with Chelsea, Chelsea wants an appointment with an exclusive stylist which Mallory has, Mallory wants someone to produce a demo tape which Hal can do, Hal will work for food...) in the Naturally Sadie episode "Whose Line Is It Anyway?".
- An Episode of Breaker High, Sean and Jimmy need kitchen access from the chef to bake a pizza, who will only give them the key in exchange for a manicure from Ashley in exchange for phone minutes from Alex in exchange for Denise repairing his shorts in exchange for some Dramamine from Max in exchange for Max's Boombox from Captain Ballard in exchange for a written note from Max forged by Tamira in exchange for a picture of Max from Cassidy, who gives it to Sean "for the school yearbook" and takes it back when she realizes what it's really for, causing Sean to continually try shoddy alternatives as the chain falls apart.
- Al from Married... with Children did this using a barter system to get a recliner. He unfortunately has to undo it to get back the shoes (the ones he usually sells and what he started the system with) when he finds that his boss is coming for an inspection.
- In The Office episode "Garage Sale", Dwight attempts to trade up to "the finest item" at the warehouse Garage Sale via one of these, starting with a single red thumbtack. This is a Shout-Out to the "One Red Paperclip" project (see Real Life, below).
- Amazingly, he's able to work his way up to a telescope, which he ultimately swaps with Jim for a packet of "miracle legumes".
- On The Unusuals, the B-plot of the episode "One Man Band" involves Casey having to do one favor after another for her fellow cops (each of which involves having to do a new favor for someone else) so she can arrange for a friend of a friend to be sprung on a minor charge. In the end, she does get him out...just in time to find out that he was actually guilty of the hit and run one of the other detective is investigating, which he can now destroy the evidence of. She fixes the situation by going to the person who requested the original favor: her father, the richest man in the city. He calls in his own favors to get her new evidence which the cops can use to arrest the guilty person.
- In Eddie Izzard's three-part series Mongrel Nation, there was a scene where Izzard demonstrated the barter system by buying lunch. Result: this trope.
- In the Frasier two-part episode "Semi-Decent Proposal / A Passing Fancy", Frasier wants to go out with a woman named Claire, but is afraid he'll screw things up. He asks Claire's friend Lana to set the two of them up, which she agrees to in exchange for him tutoring her son Kirby to a B- in History. Kirby however, refuses to make an effort, so Frasier promises Kirby that Roz will be his junior prom date if he gets a B (and keeps it a secret from Lana). Frasier then has to get Roz front row seats to a Bruce Springsteen concert in exchange for her cooperation. Naturally, this being Frasier, all the parties involved run into each other at the same restaurant, Lana mistakes Roz for a hooker, and chaos ensues. But after the chain has been unraveled and everyone has stopped yelling, in a surprising turn for a sitcom (where these kinds of incidents usually end up in No Sympathy) everyone just winds up laughing at the ridiculousness rather than staying mad at each other.
- The Law & Order episode "Kid Pro Quo": A rich pornographer wanted his kid in a prestigious private school, but was bumped out by a minority girl with better entrance test scores. The pornographer contacts a friend of his in the cement business, who gives a big price break on cement to a building developer who basically gives the headmaster of the school his apartment (which was going Co-Op, but the headmaster didn't have the money to exercise his legal right to first refusal) for free, who in turn bumps the girl for the porno guy's kid. The girl's parents complain to the Head of Admissions (who personally okay-ed the admission). She threatens to raise a public fuss if the decision isn't reversed, leading to her becoming the Victim of the Week.
- The premise of the A&E reality show Barter Kings.
- Leverage: Sophie has to run one of these in Congress to get a vote for a bill in "The Gimme a K Street Job", using a series of different aliases and regional accents.
Nate: Sophie, where are you?
Sophie: Trying to improve the air quality standards in Massachusetts.
Nate: For corn subsidies?
Sophie: No. To get me the fishery concessions that I then trade for logging rights, that get me the redistricting deal that gets me the grant funding that gets me the solar subsidies that finally gets me the bloody stinking corn subsidies. I don't know how anything gets done around here.
- An Important Things with Demetri Martin sketch portrays a particularly long and redundant chain of deals when a woman goes into labour on a plane.
- An episode of Zoey101 titled "The Favor Chain" centers around this. Zoey wants a ride to the book store to meet her favorite author, and when she asks her dorm advisor, Coco, to do it, Coco agrees if Zoey can get Micheal to cook his grandmother's raviolli recipe. Micheal will do it if Stacey will finish their school project by herself while he cooks. Zoey convinces Stacey to finish the project if Zoey can get her a date with Logan. Logan (reluctantly) agrees to go on a date with Stacey if Zoey gets his class ring back from Dustin which he lost in a bet. Dustin will give the ring back if Zoey convinces Lola to be his assistant in his magic show.

Zoey gets Chase to do it if Zoey can get a group of comic book nerds to stop trying to befriend him. The nerds agree to leave Chase alone if they can have a computer software that Quinn invented. But when Quinn can't hold her end of the deal, the whole chain of favors falls apart.
- Discovery Channel has a series called Alaskan Bush People. One episode features a needs for a generator. The deal chain involves a box of DVDs, a truckload of firewood, and some fish before the generator is brought home to illuminate the cabin.
- The song "There's a Hole in My Bucket'' features a similar situation regarding items needed to fix said bucket. It ends up looping indefinitely:
- A bucket is required, but there's a hole in it. A straw is needed to fix the bucket, but the straw is too long. An axe is needed to cut the straw, but it's too blunt. A stone is required to sharpen the axe, but it's too dry. Water is needed to wet the stone, but it needs to be carried somehow. A bucket is needed to carry the water, but there's a hole in the bucket...
- Cabin Pressure: Douglas runs his smuggling operation this way. He started with a cheese sandwich and within months has traded his way up to goods worth 500 euros.
- One episode of the children's show Jungle Jam and Friends had Millard the monkey constantly trading away what he had, never satisfied, until he finally winds up with nothing but a stick. The the stick saves his life when he falls down a well and it catches on the walls. Then the stick breaks.
- This is kind of the plot of the musical Thirteen.
- In 7th Sea the Vendel (Dutch) have a periodic competition where contestants put into a money pot and each get a small item like a pillow, sword, bag of flour, etc. All contestants have one day to do chains of deals, and whoever has the most profitable item at the end of the day gets the pot.
- The Legend of Zelda:
- Several of the Zelda games, including The Legend of Zelda: Link's Awakening and The Legend of Zelda: Ocarina of Time, include an item-trading quest of some sort. The one in Link's Awakening nets you a Magnifying Glass that will allow you to see invisible enemies, get the Boomerang, and reach the Final Boss, while the two in Ocarina net you the Mask of Truth and the powerful Biggoron's Sword.
- The Oracle games have one each to get the Level-2 sword (or Level-3 sword if you already have the Level-2 sword in a linked game). Unlike Link's Awakening, this quest is totally optional. It's also possible to avoid it entirely in Seasons. In Ages the chain of deals is to get the broken sword so it can be repaired, but in Seasons the final deal gets you a phonograph that encourages a deku scrub to tell you how to find the sword in The Lost Woods. Thus you can look the trick up on-line and avoid having to trade anything.
- The fan-made game The Legend of Zelda and the Lampshade of No Real Significance has this as the entire plot.
- Suikoden I has a classic example, where recruiting a particular member of the 108 Stars of Destiny requires you to run through a long Chain of Deals in order to get soap for a washing-woman who's run out. When you actually succeed, it turns out that she'd just discovered that she wasn't out of soap after all, but in acknowledgement of the trouble you went through to get her soap, she joins you anyway.
- Used in Golden Sun: The Lost Age, where you help a penguin cross a stream and get started in a trading sequence that takes you through every little island on the map, eventually unlocking an area with a bonus boss.
- Back before the GTS function for the DS Pokémon games was discontinued, you could do this kind of trade with real-life players all over the world - with enough careful thought about what people might be willing to trade. In about a dozen trades, you could exchange a level 6 Magikarp for a level 100 Mewtwo. (Eventually the GTS was filled with people offering low-level common Pokemon for level-100 legendaries, and the other way around.)
- An old Japanese legend tells of a man who started off with a single piece of straw, and traded up until he was rich. This was referenced in two video games:
- In Shadow Hearts: Covenant, where a sidequest starts off with a man telling the player this story and giving them a straw. Eventually, the player can trade this to get the Infinity+1 Sword for one of the characters. To be fair, it's a pretty, yet magical, steel fan, unless the player makes a wrong trade and ends up with worthless junk (or a small fortune in cash).
- The legend is referenced and inverted in Saiunkoku Monogatari, where a character starts off with money for dinner ingredients, but ends up going through a Chain of Deals ending in a single piece of straw.
- Animal Crossing occasionally forces you to go on a variant of this, in which an animal wants to get an item back from another one who borrowed it... but then you go there and discover that that animal lent the item to someone else. You have to keep following the item until you get it and can bring it back to its owner.
- It can get really weird when half the village is sharing the same handkerchief.
- A quest in Kingdom of Loathing has you getting caught in one of these while trying to get some stolen comic books back for the Gnomish Gnomads. Not only is the quest optional, the reward is rather underwhelming: the Gnomitronic Hyperspatial Demodulizer, a combat item that does a handful of damage, but gives you a brief boost to all stats if you use it to finish off an enemy. The quest also refers to one of the Real Life examples: the only item you actually retrieve yourself is the big red paperclip in the Haiku Dungeon.
- The trickiest puzzle in the original Final Fantasy I is basically a chain of deals, the difference being that not all the trades are deliberate.note This sequence is necessary to advance in the game; in fact, it all takes place before the first fiend.
- In the Dawn of Souls remake of the game, there's a Chain of Deals puzzle that involves trading things between a bunch of dwarves in order to progress in a dungeon.
- All the Mega Man Battle Network games have NPCs who want to trade BattleChips with you. Most of the trades are standalone, but in games 3 and 6, you can make several successive trades to obtain a powerful chip.
- You can screw the chain up in 6 by dumping one of the in-between chips (DublShot C) in the trader; it's almost impossible to get another one in C code. This sounds like a hard mistake to make — who puts their last one of something in the trader? — but the BN6 boards at GameFAQs get more threads asking about this than anything else.
- Ogre Battle has at least one of these in the series. The original SNES game, Episode IV, March of the Black Queen had several. The first you see is the powerful Ring of Undead, held by a wizard early in the game who would trade it for a Lexicon of Undead. And then there is the Diaspola chain. You start with some pirates with a copy of The Saga who are looking for a Map, which is in town with a man who is looking for Amatsu that can be found in the trade shop of neighboring town who only buys Furs which an underhanded sneak has and will part ways with if you give him all you money or return his stolen goblet held by bandits who want to hear a Foul Tome you received from a previous stage. Each of these items is worth progressively more than the previous.
- The desert monkey cave in Earthbound is basically a Puzzle Chain of Deals. With some lampshading thrown in ("amongst all these doors..."). Thankfully it's funny. Some players still consider it the most frustrating part of the game, mostly because every room looks like every other room and one item turns into something else (thus rendering it useless) after too much time passes. Fortunately, the player's guide (which was originally packaged with the game) eliminated most of the frustration by providing maps.
- Secret of Evermore's Greek market blatantly uses this, though it's entirely optional. It's even pretty complex, with multiple traders giving the same item for different exchanges, but the rewards you can get through it are items that permanently boost your abilities, so it's worth your time and resources.
- Romancing SaGa involved a large trade quest kicked off when Strom (Water Elemental Lord) demands the "Raincloud Armlet" in exchange for a captive princess. It's in the possession of Adyllis (Earth Elemental Lord), who will only give it up if you give him the Cyclone Shoes, which you can only get by trading the Ignigarde Helmet to Avi (Wind Elemental Lord) by acquiring the Ice Sword for Pyrix (Fire Elemental Lord) in which you must plunk down 20,000 gold or by killing a recruitable character. At any point in the chain, you can decide to brute-force the whole thing and just beat the crap out of the dragon, though and you get an awesome shield as a Item Drop. However that does have some repercussions, by killing Strom you cannot get the optimal amount of jewels for doing the quest normally, are unable to do his Ecology Quest and also getting the chance to fight his Corrupted Form; Slask (Item Drop is the Chaosbringer; A powerful 2 Handed Axe that gives an Intellect boost). This also bars you from exploring his temple later, meaning that you can't get the items inside — including the Water Spirit, which is required for another quest with fantastic rewards. Also there is a trading ability for you to use in which you can trade items with monsters; so a mini Chain of Deals is possible; Sidetracked by the Gold Saucer indeed.
- After finding the wind-up key in the crashed airship in Alundra 2, player must talk to certain characters in certain locations, trading items until last one in the chain gives the Infinity+1 Sword.
- There is an infuriating quest of this type called One Small Favour. By the time your character is halfway through building the very long chain of trades, he/she starts lampshading the ridiculousness of the whole thing. In the end, the original quest-giver doesn't seem to think getting him the original favor was such a big deal as to warrant a reward until your character goes off on him. This quest involves trading favours through twenty steps, culminating in fixing a gnome's runway lights after basically trekking in a complete path around from Port Sarim through almost every other area on the map and ending up on the other side of the world, and then going back. Then the ungrateful bastard who gave you the quest doesn't even give you a reward until you explain what you had to go through for some goddamn logs.
- There's also one part of the Fremmenik Trials quest. You end up talking to basically everyone in the entire village until you talk to someone who just wants 5000 gold. Still better than the other in that you never have to leave the village, though.
- One of the subquests in Wonder Boy In Monster Land is this; start with a letter and finish with either a solution to the final dungeon (very handy - that place is a non-logical maze) or a trinket that will take off about a third of the final boss's health instantly (even more handy - if you're properly kitted out, the final boss isn't difficult to kill, making running out of time the biggest problem).
- A rather extensive example occurs in the original Paper Mario, where you deliver letters and get letters in return with the help of Parakarry. The errand has you deliver letters to NPCs from Chapter 1 to Chapter 7, and completing the sidequest nets you the Lucky Day badge, an item that greatly increases evasion.
- In Super Paper Mario, Merlee wants a crystal ball from Merluvlee, who in turn wants a training machine (actually a DS) from Bestovius, who in turn wants a mysterious DVD (implied to be porn) from Watchitt, who wants an autograph from Merlumina, who wants to go to sleep. Eventually, her long speeches bore you to sleep, causing her to get sleepy, leading to you completing the chain. Merlee repays you with a free charm and a key that allows you to unlock the Pixl Piccolo.
- Similar side-quests also happen in the first two games, both of them involving the aforementioned "secret DVD" (originally a tape). My, what lazy censors.
- Browser-based MMORPG Travians includes several of these, and finally throws in a Lampshade Hanging:
Tombo: Oh, you're up to your strange swapping deals again?
- The old game Hacker required you to send a robot around the world trading items to obtain pieces of a secret document, while figuring out how to avoid the security checks on the system you were "connected to".
- Planescape: Torment: You want information on Ravel? OK, you just need to talk to Ecco, except she won't talk to to you at all, so maybe you should talk to Dolores who doesn't want to talk to you unless you get something from Merriman, who wants to forget, so you need to get a Stygian shard, which you can't pick up without a very special cup that you can get by curing a wizard-reject's alcoholism. Oh, yeah. You have to figure out half of these on your own too.
- In the Age of Empires II Mongol campaign, the first scenario involves you riding around trying to coax several different tribes to join you (except one, which is stated as being 'without honor' for no apparent reason). Most of these tribes ask you to do something for them in exchange, often something you can't do until a different tribe joins you. For example, one tribe wants you to bring them a relic, and only monks can carry relics, so you have to get the tribe that gives you monks to join first.
- Dark Cloud has one of these. The chain begins with a pink lollipop and ends with the single most powerful weapon upgrade attachment in the game.
- Jays Journey has one spanning most of the game, most (but not all) of which is required to complete the game. Jay sees the trope in progress and is more than happy to make bad deals, because he knows it'll all work out in the end. (He gets a bit annoyed when NPCs are slow to give rewards, or when one NPC tries to steal the trade-item-of-the-minute, however.) All of the items have an identical description: "Some trade item".
- Breath of Fire IV has this, too. In fact, it's needed for one of Ryu's Dragon forms.
- Dungeon Siege II has a chain quest that spans virtually the entire campaign.
- Dr. Doom does this behind the scenes in Marvel Ultimate Alliance, and you spend the entire game trying to catch up.
- In Family Project, Chunhua gets a free piece of candy on the street as an advertisement and gives it to Tsukasa. Tsukasa trades it for a pack of cigarettes. He gives the cigarettes to a guy on the street and gets a 5000 yen gift certificate. He uses that to pay Masumi's debt at some store or another, and she gives him thirty lottery tickets, enough for three tries at a game. Chunhua tries three times and eventually gets a personal computer worth 300,000 yen. Lampshaded.
- One of these shows up in Final Fantasy Tactics A2; you're not doing the Chain of Deals, rather you're one of the people in it. You get to see the guy royally screw it up: The step is adamantite for a vial of silver liquid... and silver liquid melts adamantite on contact. Poor sap forgot to wash his hands.
- Russian quest game ""Last Year's Snow Was Falling'' had a subversion of that. Once you understood the 5-step chain of deals and tried to grab the starting item, you were carried away to the next location.
- In Dubloon, you must trade items on Stern Island to get the map location of East Sea Serpent.
- Due to the introduction of player-to-player trading, Team Fortress 2 can have thousands of people simultaneously attempting various self-invented chain-trades. In order to get a certain hat for your friend, you have to go to someone else who has that hat, and who wants some other hat that you can get from another friend, etc.
- Some players have done Red Stapler trading sequences, often managing to climb from a crate to something incredibly valuable.
- There is actually a whole theoretical model built upon this: Various players do things called "Scrap Banking". For Scrap Banking, the Banker pays 1 scrap for any 2 weapons. In the crafting system, 2 weapons can be turned into 1 scrap if they are from the same class, so in theory the Banker is not loosing any "revenue". He then sells the Weapons for 1 scrap each, effectively doubling his scraps with each pass. Any unsold items are crafted into scraps, combined with the others and re-"banked" into more weapons. Rinse and repeat. The problem with this, however, is that any player that can trade (those who have gotten a full version of the game) knows the values of expensive weapons, and would attempt to sell them on their own. The only weapons they'd scrap bank are ones everyone already has, or are widely abundant. This means that very rarely will this work, and if it works, it's only going to net you a very, very low net gain for the effort you put in.
- With the introduction of Steam Trading, you can now potentially trade up from a lowly, common crate all the way up to a $60 dollar game like Deus Ex, provided you get lucky enough and find the right buyers.
- Edutainment Game Spanish for the Real World has one activity where the player is given a basket of fruit and a list of (different) fruits s/he is supposed to get, and must trade with the various people at the market for them, leading to this trope. (For example, you have an apple and need to get an orange. However, the person who has an orange only wants a banana, so first you have to trade with the person who has a banana, who wants two lemons, so first you have to trade with the person who has lemons...)
- The game Darksiders and its sequel features a continuous array of deals that propels the story.
- The Spirit game, Spirit: Stallion Of The Cimarron: Forever Free features one near the end. In exchange for a horse's freedom, someone wants a wheel to fix their cart, the blacksmith who has a wheel wants a blanket from Little Creek, Little Creek in turn wants an axe to chop wood with...and said axe can then be
stolentaken from Snakefinger.
- This can happen between three or more players in Heroes of Newerth's and other Defense Of The Ancients clones' Single Draft mode where every player is given a choice from three random heroes that can be swapped between other players in your team.
- In the first series of .hack, one of the least favorite side-quests was to help someone with their trading service, which quickly went horribly wrong because nobody can do an even trade, and one more item had to be fetched in order to even start the chain of deals. Everyone lampshades how irritating this is.
- An obscure point-and-click adventure entitled The Day The World Broke has a doozy of a chain. To get Carbine the half-Lizard, half-camera (all the non-human characters are half-animal, half-machine) to stop standing in the path of an element valve, which is causing chaos across Earth's surface, you need to fix his lens. The only place to get a lens is the Glass Works, where Carbine doesn't have the best reputation. That's a moot point, though, as the Glass Works is too busy filling orders for new glassware for Lugnut the bartender. So you need to get a note from Lugnut, who'll give it to you in exchange for getting rival bartender Decanter to part with rare bottle of sludge. In order to get that, Decanter wants a recording of a song his mother used to sing him, which requires an instrument that's notoriously difficult to find but fortunately is in the hands of one of Lugnut's customers, Ratchet, who will trade it to you for another instrument which actually doesn't exist, so you need to enlist the help of Phlange, who will help you make something that could pass for it, but in order to get Phlange to help you, you have to get her to stop standing in a different element valve. To get her to do this, you have to call Julius and Bud at Mission Control, who will finally convince her to leave, allowing you to get her help to make the instrument to trade for the other instrument to trade for the recording to trade for the sludge to trade for the note to trade for the lens. Whew.
- Indiana Jones and His Desktop Adventures, using randomly generated puzzles, often ends up setting up several Fetch Quests in a row. Bring a Demon Mask to the amateur archaeologist so that he will give you the Obsidian Knife, which you'll give to a native who'll give you a Headdress, which you'll give to a tourist in exchange for a Jaguar Statue, which you'll give to another native in exchange for a rope, which—finally—will be used in an environmental puzzle instead.
- The Last Story has one that starts with a lunch bag (mandatorily received after a main mission), and concludes with receiving a rare katana in a subterranean prison.
- In MARDEK Chapter 3, you can find a rare fruit in an underground desert. Giving the fruit to a reptilian shopkeeper gets you Special Ointment, giving that Ointment to a bald priest gets you Hair Tonic, giving that Tonic to a different priest gets you a Romance Novel, giving that Novel to the Princess of an Air Temple grants you a Cake, giving that Cake to a hermit hiding deep in a volcano gets you a random key, that random key opens a random chest in the Earth Temple, that tiny random chest hides a gigantic red dragon, beating that dragon gets you its scales, you can take those scales to a reptilian blacksmith who'll forge you the Infinity+1 Sword for your reptilian party member. There's no way you'd ever figure this out without the Mardek Wiki or Official Walkthrough.
- Star Wars: The Old Republic parodies the way this trope is often played in RPG sidequests: upon arriving to Dromund Kaas City as an Imperial character, you are directed by an Imperial Intelligence operative to say a code phrase to another agent on the other end of the city, who then asks you to deliver a gambling chip to a third agent elsewhere, who tasks you with finding a specific droid... Ultimately, the entire wild goose chaise proves to be a ploy by the Intelligence to get the attention of the Republican spies in a bid to lure them out of hiding.
- Robopon has the Fetch Quest to get Golden Sunny/Silver C-Cell, which plays out like this.
- Mass Effect 3: You need to unify the main Council races against the Reapers. The turians aren't able to come unless the krogan can be brought to the vicious fighting on the turian homeworld, since the krogan are the most powerful ground-fighting force the galaxy has ever seen. The problem is that the krogan hate the turians and the salarians for hitting them with a sterility plague 1500 years ago, and have their own problems with the Reapers, although less of one; they refuse to come unless they get the genophage cured and ideally the Reaper scouts are dealt with. Thankfully, the salarians can be coerced into handing over the closest thing to a cure they have, although unless you sabotage the dispersal they'll sulk and refuse to commit to the mutual defence pact unless one of your friends saves their Councillor from assassins - and if you do sabotage the dispersal, you risk losing a lot of krogan support if the truth comes out.
- Child of Light has a rather short one where a mouse merchant challenges Aurora to "turn an apple into gold". It involves passing an apple to a teacher to obtain his shovel, passing the shovel to a digger for a lantern, then passing the lantern to a mouse miner to obtain the gold.
- Sands of Destruction features a couple:
- When you visit the Sky Gaol for the second time, several of the prisoners ask you to pass letters and packages between then (why none of them ask you to go find the guard with the keys is never mentioned). Completing the chain nets you a few good items.
- Talking to certain beastwomen in various towns around the world will have them comment on Morte's good fashion sense and gift her with a gaudy piece of armor. When you find the next woman, she'll take the last piece from your inventory and give you a new one more outlandish than the last.
- Grisaia No Rakuen has an example where the person making the deals has not the slightest idea what she's doing because she's just following the directions of a dopey sounding computer. In the morning, with a thousand yen Michiru buys thousands of discarded cellphones. She has the rare metal stripped out and sells those and then uses the money to go up increasingly complicated chains often involving being flown around to separate countries and trading boats or beers for people. Very late at night, she returns home with no clue where she's been all day, only knowing that she's had a growth on her initial funds of at least 10000%.
- Parodied here by 8-Bit Theater.
- The first Skin Horse storyline featured an increasingly absurd chain as main character Tip tried to deal with an increasingly bizarre string of escaped/lost sentient lab experiments.
- Which proved to have some consequences, since he ended up screwing up the whole chain of deals his boss was used to dealing with - which resulted in her having to find out if the new leadership down in the basement is amenable to talking with the folks upstairs. Lampshaded at several points during the whole chain.
- Slightly Damned provides its take on these.
- Featured in Gold Coin Comics, starting here, where it begins with a crappy belated birthday card.
- Awkward Zombie lampshades the ridiculousness of Zelda examples here.
- The SMBC Theater sketch Internet Bartering parodies the One Red Paperclip example nicely.
- Episode 9 of My Little Pony: The Mentally Advanced Series. Twilight needs holy water from Pinkie, who wants vengeance on Fluttershy, who wants her hairbrush back from Rarity, who wants Applejack to lend her some farm hands for her work. Eventually Subverted: in the end, Twilight can't remember who wants what or why, and instead gets some holy water from the mayor.
- The Ed, Edd n Eddy episode "Who, What, Where, Ed!" featured a Chain of Deals that started with Eddy trying to get a chicken egg from Rolf, who wanted sawdust they had to borrow from Kevin, who wanted paint they had to borrow from Jimmy, who wanted clams they had to borrow from Johnny, and so on, driving Eddy closer and closer to insanity (as well as Lampshade Hanging) with every turn. The chain goes to Jimmy twice, they're forced to get something different from Johnny than he first asked because they couldn't get it from the Kankers, and eventually stretches back to Rolf. And while the Eds finally resolve the chain, Ed breaks the egg the second they get it because he thought he needed to set the chicken inside free.
- In one of the "Lord Bravery" segments of Freakazoid!, Lord Bravery is given a Cease-and-Desist order on his name, as it was first used by a bakery. As it turns out, the bakery resorted to Lord Bravery because the name the owner wanted to use was already taken. The owner offers to give Lord Bravery back his name if the owners of the business with the name she wants will give it to her. This leads to a ridiculously long chain of businesses with ludicrously inappropriate names that ends only with the discovery of a shop owner who is quite happy with his business' name, causing the chain to collapse.
- And forcing Lord Bravery to change his monicker to Lord Smoked Meats And Fishes, making people respect him even less than they did before.
- This was also the basis for the Looney Tunes short Leghorn Swoggled, with Henery Hawk making a long string of deals in order to catch Foghorn Leghorn. After making a bunch of deals (dog wants a bone, cat knows where to get a bone but wants a fish, mouse knows where to get fish but wants cheese) he remarks "I wonder what the cheese will want?"
- Also happens in Dime to Retire, where Daffy runs a scam in the hotel Porky is staying at. First, he let a mouse into Porky's room, which drove Porky nuts by eating a piece of celery, prompting him to have Daffy bring in a cat to chase it off for a mere $5, only for the cat to refuse to let him sleep on his bed, thus Daffy brought a dog to scare it away for $10, only for the boxer (after hearing a bell, courtesy of Daffy) to start punching Porky, after which Daffy charged $26 to bring in a lion to get rid of it, which naturally tried to eat Porky, then for another $72, Daffy used an elephant to drive out the lion, however, the elephant then took up most of the room, so for $666, Daffy released the mouse back into Porky's room to scare it off, leaving Porky with the celery-eating mouse all over again.
- The Life and Times of Juniper Lee, "It's the Great Pumpkin, Juniper Lee": June manages to successfully complete a Chain of Deals to un-spell a few monsters. One of those "deals" involved winning a wrestling match.
- In an episode of Recess the gang arrange a Chain of Deals to enable Mikey to achieve his dream of becoming a crossing guard. The chain works perfectly, but when it starts to rain Mikey decides he doesn't want the job after all.
- Parodied on Two Stupid Dogs. An off the hook payphone tells the dogs to get a quarter, so they go to a change machine, but they need to get a dollar. This leads them on a quest to get larger and larger sums of money, each of which is eventually traded in for a smaller amount right down to the quarter.
- Which is then used to phone the larger dog, in prison with a $10,000 bail.
- Chowder goes through a Chain of Deals to retrieve his lost hat, but accidentally gives the hat away in the process, requiring an undoing of the chain... and a redoing... and another redoing... and it's all done in song. (Lampshaded at the fourth stop, when a giant says "I'm beginning to see a pattern here...")
- In an episode of House of Mouse, after accidentally spending the rent money on cheese, Mickey is in desperate need of $50. Merlin will give Mickey $50 in exchange for a sword for Arthur, The Headless Horseman will give Mickey a sword in exchange for a pumpkin to use as a head, Cinderella will give Mickey a pumpkin in exchange for an alternate ride home, Aladdin will give Cinderella a carpet ride home if he can get a rose for Jasmine, Beast will give Mickey an enchanted rose in exchange for a book for Belle, and Yen Sid is in no mood at all to share his books, scaring Mickey off and throwing the whole chain apart.
- A U.S. Acres segment in Garfield and Friends had Orson wanting to get Bo a record player. Booker has one but wants a skateboard. After failing to hit Roy's three practical jokes, one of which involved super-hot chewing gum, Orson convinces Roy to part with his skateboard in exchange for a pie. Lanolin is willing to give up her pie for a stepladder. Wade is more than happy to get rid of his stepladder, but Orson insists on giving him something... specifically, the spicy chewing gum he got from Roy. When Wade realizes how horrible the gum is, he takes back his ladder, causing the whole chain to temporarily reverse.
- An episode of Jimmy Two-Shoes had Jimmy go through one to get Beezy's collection of chewed gum back.
- In Dave the Barbarian, Candy owes a huge debt to a troll, who agrees to cancel it if they can collect the money that Chuckles owes him instead. Chuckles doesn't it, but says the Queen of the Mole People owes him money. She, meanwhile, has a debt from the original troll. In the end, Candy just has the troll write a check; they pass it around until it gets back to the troll, thus settling all the debts. Then they sing a song about an egg named Steve.
- In Futurama, the Robot Devil accidentally trades his awesome robotic hands for Fry's stupid human ones, allowing Fry to become a musician and impress Leela. Since Fry won't trade back, the Devil goes through a chain of deals until he gets Leela's hand in marriage, which Fry is willing to trade for.
Robot Devil: Ah! My ridiculously circuitous plan is a quarter of the way complete!
- In the Phineas and Ferb episode "Tri-State Treasure: Boot of Secrets", while at a swap-meet Candace tries to get an extremely rare Ducky Momo antique. The seller will only trade for another antique found at the swap-meet and what follows is Candace doing an extremely long chain of trading with very bizarre sounding items. Despite her efforts, she still doesn't get the antique due to Doofenshmirtz's Inator ruining the antique she was going to trade for it.
- In the The Penguins of Madagascar episode, "Operation: Good Deed", Mason's back gets injured by a bucket and he needs a massage. King Julien will let the Penguins borrow Maurice, who gives excellent massages, if they can get him a flamingo feather for his crown, Pinky will give them one of her feathers in exchange for some peanuts, Burt will give them his peanuts in exchange for some hay, Roy will give them his hay if they can get Bada and Bing to stop throwing their banana peels into his habitat, and Bada and Bing will stop throwing their banana peels if they can get them a pizza.
- Baloo and Kit invoked one in an episode of TaleSpin where they flew odd cargoes around the world, opting to always turn down the offered cash at his destination and instead trade it for another odd cargo. Much to the disbelief of Kit, as the refused cash offers keep getting larger, and it was his money that started the chain (with the promise of getting double the money back). The final cargo they pick up is seemingly worthless, but upon returning to their point of origin, it's learned that it's actually a very rare and valuable commodity and they net a small fortune selling it. Unfortunately, a pair of gangsters they annoyed at the start of the episode then show up, and in the panic to escape, they lose all but double the original money they started with.
- Rainbow Dash & Fluttershy's portion of the My Little Pony: Friendship Is Magic episode "Trade Ya" features Rainbow Dash going through such a chain to get a first edition book she wants to complete her set. The trade includes Rainbow Dash trading her lucky horseshoe for a crystal chalice; the crystal chalice for an antique chicken statue; the antique chicken statue for a Discord lamp; the Discord lamp for an Orthrus; and finally, the Orthrus (along with Fluttershy as a trainer) for the Daring Do first edition book.
- The impracticality of this in large-scale societies is one of the major reasons (the others being transportability and storability) for introducing currency* , as opposed to relying on barter for trade. With barter, you have to find someone who both has something you want and wants something you have in order to make a trade (you have berries and want pies but the pie maker doesn't like berries), while with currency you only have to do the former because you know almost everyone will want currency.
- Star Trek reviewer SF Debris went into this topic at some length while reviewing a DS9 episode about a Chain of Deals. He pointed out that although the Federation claims to have eliminated money and the need for money, clearly people still have needs or desires that cannot be met except through exchange of goods and services, and that the absence of an accepted currency just makes the whole thing wastefully inefficient and even comical. He also points out an Accidental Aesop: Since Jake has never used money, he has no comprehension of its value, which is why he thoughtlessly badgers his best friend into trading away several years' worth of savings on a baseball card.
- Wondering about the page picture? As documented on One Red Paperclip, in the course of one year (July 2005 to July 2006) Kyle MacDonald negotiated a Chain of Deals that started with a single red paperclip and ended up with a house — in only fourteen trades! And now he's putting the house up for trade. Someone get this man the Infinity+1 Sword. Incidentally, he borrowed the paperclip back. To bend into an engagement ring to propose to his wife.
- For the compressed summary of his deals, he traded the paperclip for a fish pen for a doorknob for a barbeque for a generator for an 'instant party' package for a snowmobile for a trip to Yahk for a cube van for a recording contract for a year in Phoenix for an afternoon with Alice Cooper for a KISS snow globe for a movie role for a house.
- Daisy chain for kidney donors. Someone in need with of a kidney may have a friend willing to donate to him, but who isn't compatible. So the healthy friend signs up to donate a kidney to anyone that needs it if his sick friend receives a kidney. The result can be a complicated Chain of Deals (all thankfully arranged by sophisticated computer algorithms) in which multiple pairs of friends (recipient and incompatible donor) trade kidneys with other pairs until everyone receives a healthy kidney. The longest such daisy chain of such chain involved 11 people receiving kidneys, all from one non-directed donor offering his kidney to whoever needed it starting the chain. In case anyone is interested they can sign up to be start their own chain of kidney deals (and officially become badass) here.
- In the residential housing market, many sale contracts are conditional on the buyer's current home being sold. This means a situation can arise where the sale of a home is dependent on the sale of another home, which is dependent on the sale of another home, etc. making for a very long chain of held up contracts. When the last seller finds a buyer who is not tied to selling a current home, the entire chain of contracts go through very quickly thereafter.
- Without getting into specifics, players of any kind of Collectible Card Game (or, indeed, collectible anything-that-comes-randomly-blind-packed game) have likely committed to a three-or-more-way trade in order to get that last card for their precious deck/army/complete expansion set.
- Interestingly, electrical power systems are often protected by a chain-of-deals-like system. In interlocking, you must satisfy certain conditions in order to operate an item of equipment (disconnectors, earth switches, access gates etc.) which involves following prescribed sequences of opening/closing switches to obtain keys to access other sequences to obtain another key that opens the shutter to the hand crank you need to operate the item of equipment you were interested in the first place. For added super-bonus fun, on offshore windfarms certain steps entail sailing between individual turbines, key clutched in hand. The reason for this intentional complexity is to ensure that all equipment is made safe before anyone gets anywhere near it, and that there is no danger of damaging the main grid.
- Medieval Trade tended to be an extremely complex chain of IOUs spreading from India to Europe and beyond, known in English as bills of exchange. They're the ancestors of modern checks, and could involve money, but as often as not they just directly involved traders swapping goods.
- Certain stores offer perks for money spent, such as discounts on fuel from their branded stations. Some will apply this to gift cards and even point out in their commercials that you can use this as a way of getting bonuses on items that you ultimately purchase somewhere else. Naturally, there will be a limit to what stores they offer gift cards for, but if one of those stores happens to carry the gift cards for another store...
