I worked at a Walmart years ago and would get so annoyed when I would be putting up my department returns and find items with a competitor store price sticker on it (that business was literally at the opposite end of our parking lot). When I brought it to the store managers attention, he told me about how people spend something like 30% more than the amount they are given on store gift cards, so its whatever to them. I’m not suggesting you take back an item you can’t sell, but that stuck with me for 20yrs now lol
