Why some sellers are so stingy???

This is a rant and wanna know what yall think…
But I swear I’m gonna stop using this app

I wanna know why so many people feel so entitled to charge ridiculous overpriced items and always decline offers on items they aren’t moving at all…

When I was selling stuff I would sell everything for $30 or less but in some cases I see some people charging $200+ for a used sweater

Mind you I gotten very lucky I recently bought an authentic designer shirt for $100 from an offer and that dude was a total angel…

BUT WHY there’s so many people selling used Heaven by Marc Jacob’s items like if they were the ones making that item themselves…. I rather buy from Mr.Marc Jacobs himself than support these stingy people like wtf
