Everyone’s opening a resell/vintage store but with ridiculous prices!!

Why is every resell/vintage store selling shoes and clothes for 5-10x the amount?! And people still shopping there is what gets me. What I wanna do is open a resell/ vintage shop. Dunks won’t 300 bucks, Shoes won’t be stupidly priced high, they’ll priced to where everyone can buy them, same with the clothes. I just want a fair store that’s not about money 💰. I want to try to balance this stupid resell stuff!!
