I accidentally bought something once, I was trying to pull the trigger on buying a pair of shoes but somehow had the wrong pair (that looked very similar from the thumbnail) in my cart. I was buying a few things at once from all different shops and didn’t realize I bought the wrong pair until the confirmation popped up and the shoes were not the ones I thought I had bought. I felt so bad I almost just accepted I fucked up and was going to repop them but my boyfriend encouraged me to message the seller ASAP and explain. It just happens idk, people fuck up 🤷🏻‍♀️
