Inverted in this trailer. Apparently the devil sold himself to our protagonist.
Dr. Horrible's Sing-Along Blog: an interesting twist version of the Ordeal, where the Mephistopheles's offer to the Faustus is, effectively, to help rule "Hell" if he'll just kill one person, anyone... the Faustus accepts, believing he will be able to use this authority to reconstruct a better world, but by carrying out his assignment ends up abandoning his original motivations, ethics, and, indeed, everything he ever made the deal for in the first place... which was, presumably, the point of the ordeal to begin with. Ladies and gentlemen, Dr. Faustus: The Musical!

The result was that the demon ate all three and proceeded to start hunting virgins in Los Angeles.

In the DVD review of "The Review Must Go On", he mocks and acknowledges that it's played more like Doug selling his soul to the Critic-devil rather than just bringing a show back.
Nothing gets Linkara into an angry rant like One More Day, in which "Spiderman! Makes a deal! With the devil!!!" It has almost become one of his Catch Phrases.
In Dark Dream Chronicle, going through Session gives you enhanced strength, stamina, endurance, brainpower, you name it, all at the low low price of giving your Soul to "the Master". Also, if you aren't Immune, you die horribly around the age of 27. Oh, and if you get picked to be an Enforcer, you get all of your emotions removed. Have fun~
SCP-738. The price paid for a deal is something intended to cause emotional pain to the person making the deal, like the death of a best friend or losing all memories of one's mother. Interestingly, when a test subject who is severely mentally handicapped is sent in to make a deal, the entity accepts it... but then sighs in regret once it's complete. And when they sent one of their lawyers in, the result was a 900+ page document detailing the terms of the deal, which didn't even get finished because the lawyer collapsed from exhaustion after spending 41 hours negotiating with the entity. When the lawyer woke up, he found a note in his pocket: "Please come back any time. I haven't had so much fun in years."
SCP-2791 ("Fauste Bank plc"). When someone wants to make a deal with the forces of Evil, they can use the services of SCP-2791 to avoid the nasty consequences of doing so.
A group of aliens, eventually classified as SCP-ES-007, from the Spanish section of the site, came to Earth from Europa seeking the entity's help, calling it "the trickster, the dragon charmer, the inconceivable, the ineffable, the rite", which trades anything for some thing he finds attractive. He also mentions it's not the only one, that no one knows why it does whatever it is that it does or even how, and that it has altered its shape many times from whatever Time Abyss spawned it. While the observers were not privy to the details of the discussion, the poor guy collapsed in despair after finally talking with the entity.
This news story from The Onion suggests that Beyoncé made a deal with a witch for talent and fame in exchange for her first child. And as soon as Blue Ivy Carter was born...
In Fate By Blades there is a devil-esque figure who makes deals with mortals, often with the condition that someone involved with said deal take a Horny Devil consort. The opening antagonist, Gilliam, does this but later breaks his end of the deal, causing his whole rebellion to fail, while Lucas makes a similar deal to acquire a demonic consort to tempt Kona over to his side. Lucas is more successful as Kona ends up joining him.
Kyle from Statless And Tactless considers any deal made with Joe to be a devil's bargain. The fact Joe is clearly evil and makes his posts in red text doesn't help.
The Cleanser from the Sporewiki Fiction Universe seems to zig-zag this trope. On one hand, he often grants people deals in exchange for their souls. On the other hand, he uses his ownership of your soul for benevolent purposes, and, though he often tricks you, he does so to maximize the benefit he gains from the deal, and any harm this causes you is merely a side effect. In addition, most deals with him are stated to go fine.
To make it even more confusing, he does collect the souls he owns after their deaths and put you in a lake filled with lava and instruments of torture, but, once he feels you have made up for your accumulated sins, he alters you such that this results in orgasmic pleasure rather than agonizing pain.
Ultimately, whether or not a deal with the Cleanser counts as a deal with the devil depends on whether or not you view the Cleanser as a good or evil character.
According to SF DebrisJaneway became a Starfleet captain by sacrificing the souls of Omicron Theta to the Devil (by means of the crystalline entity), and has him on speed dial. It's definitely a business relationship, because she dismisses the advice of her shoulder devil as "religious crap".
