Donna: Jackie, it's Tuesday.
A subtrope of Room Shuffle.
A stock excuse for going out, when a character either doesn't want to give the true reason or is leaving not to return, is "I'm going to the store". In Manga, Anime and other Japanese media, the store in question is likely to be referred to as the konbini; i.e., the local convenience store open at practically all hours.
One reason this trope is a lot more prevalent in Japanese media is that they don't have a lot of space in their homes for storage, and convenience stores sell more kinds of things, so it happens more in Japan.
In the U.S., though, going to get cigarettes or milk or "the paper" is often a convenient excuse to get a character away from the others for a while, and as there are convenience stores that are open 24 hours a day, too, it's not a major expedition, so one character may go alone.
- Great Teacher Onizuka: When Anko goes out to meet Noboru, she tells her mother that she's going to the store. Her mother wonders "You took a shower to go to the store? And is that my perfume?"
- The Girl Who Leapt Through Time: Makoto uses it as a pretext to go out to test her time-leap ability.
- Inverted in Kimi to Boku. When Kaname gets annoyed at his mother bothering him while his friends are over, he tells her she should go to the store to buy food for dinner. Then she asks him if he would go with her.
- Happens in the Fresh Pretty Cure! movie. For all four girls. So they can investigate odd goings on involving missing toys. Love's mom questions why all four have to go out at the same time for one little item.
- Kaoru did this in the anime version of I Can't Understand What My Husband Is Saying (in the manga version she claimed that she was stepping out for a smoke) when she felt unsure about her compatibility with her husband.
- In the comic strip Stone Soup, Joan's ex-husband Leon went to the store for some milk and didn't come back. Rumor has it that the store was in the Bahamas.
- Betelnut Beauty: Fei-fei, about to run away from home, claims she's going to the convenience store to get past her mother.
- In Corrina, Corrina the titular character's husband left to the store to get cigarettes and never came back. The little girl, upon being told this, is afraid this might happen to her dad, who smokes.
- In Cinderella II: Dreams Come True, Anastasia tries to improvise a reason for visiting Dimitri the baker by grabbing some bread from the pantry, tossing it out the window, and telling Lady Tremaine that she has to go buy some more.
- A variant in American Psycho, where Patrick's go-to excuse for exiting a conversation is "I have to return some video tapes."
- Jackie uses this excuse in one episode of That '70s Show (she actually goes to make out with Hyde).
Jackie: Um, you know, I just remembered that I have to go to the mall because they're having this big Monday Madness sale.Donna: Jackie, it's Tuesday.Jackie: See? Total madness!
- It was a cliché in mysteries for a long time: "What really happened to your husband, Mrs Quigley?" "He went out to get cigarettes six years ago, but he never came back!"
- iCarly uses this quite often. One of the more blatant examples is shoving Sam out to buy meat, so that Carly and Freddie can discuss the face he's not had a real First Kiss. Only for Sam to realise she has no money, and come back and overhear the conversation.
- While slipping out for some slaying in "Living Conditions", Buffy tells her college roommate that she's going for coffee. In the middle of the night.
- In their live cover of The Doors' Roadhouse Blues, the Blue Öyster Cult front man Eric Bloom uses his trip to the store to set up the key line in the song, first by namechecking Los Angeles (huge roar from crowd), then rapping on checking into the hotel, finding out room service was closed, and being forced to go out to find an open seven-eleven. He gets back to the room and falls asleep before he can consume his purchases. What did he do?
I woke up this morning and I got myself a beer!
- Carly Rae Jepsen does a variation of this on "Store" (from her EMOTION: Side B EP). Unlike most uses of this trope, it's from the point of view of the person who's leaving.
Oh, I can't talk about it, can't talk about it causeI'm just goin' to the store, to the storeI'm just goin' to the storeYou might not see me anymore, anymoreI'm just goin' to the store
- A variation in Bruce Springsteen's "Hungry Heart":
Got a wife and kid in Baltimore, JackI went out for a rideAnd I never went back
- Ray Romano discussed how he would volunteer for chores if he needed to leave the house. These included stopping by the DMV or applying for jury duty.
- Similarly, Louis CK has a story that starts: "Once, my wife sent me to the store to get toilet paper. Because we were out of toilet paper. Because I had thrown it all in the garbage so I could get out of the house."
- In The Fairly OddParents!, Cosmo's mother didn't approve of his relationship with Wanda. To hide their marriage, Cosmo had to give her an excuse to leave. He told her he was going out to get milk. Cosmo and Wanda have been married for 10,000 years.

- In The Powerpuff Girls (2016) episode "Super Sweet 6", everyone in Townsville is invited to Princess' 6th birthday except for Blossom. Blossom's family decides to stay, but they all (not-so) secretly want to attend. The Professor lies and says he's going to the store to buy water, but he actually went to Princess' birthday bash. This in turn causes Blossom's sisters to use also use excuses to go to the party.
- This is a Christmas Dead Horse Trope (or possibly a Dead Unicorn Trope) in Sweden. On Christmas Eve, the father in the family uses the excuse of "I'm going to the store to buy a newspaper" to sneak off and dress up as Santa Claus.
- Played for laughs in a Christmas special where Santa ended his visits by going to the local store to tell all the dads they could go home now.
