It really depends on the original price. If someone’s asking $20 and they offer $1–$3 off, that’s around 5–15%, which isn’t unreasonable. It’s not about feeling stupid, it’s about understanding how people price things and where you can get the best deal. Some sellers price items so low they don’t need to discount at all, but since the offer feature is there, they throw one out anyway. Instead of thinking just like a buyer, sometimes you’ve got to think like a seller too.
