Well, my wife had an accidental shopping spree at a makeup store. She was attracted by all the new products. She ended up buying several lipsticks of very similar colors. Also, she once went to a bookshop and bought a whole series of books she already had some of, because she didn't check her collection at home before buying.
My wife once went shopping and accidentally bought two pairs of the same shoes. She just didn't notice when she was at the store. Another time she came home with a bunch of clothes that she thought were on sale but actually weren't.
My wife's accidental shopping spree was quite something. She went to the supermarket to buy a few things but ended up with a cart full of items she didn't really need. She saw some 'buy one get one free' offers and just grabbed without thinking. And once she bought a really expensive dress that she thought was a different brand with a lower price.
Imagine a fanfiction where Naruto has a day off and decides to go on a shopping spree. He starts at the local bookshop, looking for any new scrolls about ninja history or jutsu. After that, he visits the pet store and contemplates getting a little pet to keep him company in his apartment. But he realizes he's not quite ready for that responsibility yet. So instead, he goes to the art store and buys some paints and canvases, thinking he might take up painting as a new hobby.
A naive wife might go shopping and end up buying things she doesn't really need just because they look cute. For example, she could see a bright - colored hat with a big flower on it and buy it without thinking if it actually goes with her wardrobe.
A Harry Potter shopping spree in fanfiction would likely involve a lot of exploration. The character could go to Knockturn Alley to find some dark and mysterious items, like a cursed object for a story's plot. They'd also visit Weasleys' Wizard Wheezes and buy out all the funniest and most inventive prank items. It would be a chance to really immerse in the magical shopping world of Harry Potter, getting all the things that make the wizarding life so exciting.
In fanfiction, it could be a young witch or wizard who just got their Hogwarts letter. They're excited to get all their school supplies and some extra treats.

One time my wife was trying to make a simple pasta dish. She accidentally put salt instead of sugar in the sauce. It was so salty that we couldn't eat it at all. Another time she burned the cookies because she got distracted by a phone call.
A Naruto shopping spree fanfiction could involve Naruto being accompanied by his friends like Sasuke and Sakura. Sasuke would be all grumpy about the whole shopping idea at first, but Naruto would drag him along. They'd visit stores selling rare ninja artifacts. Naruto, being his impulsive self, would want to buy everything he sees. Sakura would be the voice of reason, trying to stop Naruto from overspending. Meanwhile, Naruto would also be on the lookout for gifts for his sensei, Kakashi. He might end up buying a super expensive and rare book on ninja tactics for him.
Trust your instincts but also look for evidence. Don't jump to conclusions right away. If she says it was an accident, try to verify it in a non - accusatory way. Say, if it was about her being in a situation with another man, you could ask to see any related emails or messages to clarify things. If it was truly accidental, work on rebuilding the trust. This might involve going to couple's counseling to address the underlying issues in your relationship that led to this misunderstanding.
One such story could be when a wife accidentally sends a flirty text meant for an old friend to her husband instead.

Your wife could have had a really helpful salesperson at a store who went above and beyond to assist her.

A wife once accidentally double - booked her evenings. She had promised her husband a date night but also had made plans with a group of friends from work that included some male coworkers.
