IDK? Who should be blamed? Or have the worst ? But, I'd go with scalpers , The buyer can be an uneducated mom trying to buy his son a PS5? I've seen Xbox One X sell for 600 dollars in 2021 , doing their "hook line and sinker" "mumurs sucker. And in his description say's "No returns" which I find in Facebook stores.Not all are easily tricked? It's usually Parent's and those who don't research in Price charting , That impulse buy.
If you can just impulse buy something at 1500 bucks, I dont think youre much of a victim of anything. Its not really difficult to find out what something is worth. They could start by asking their kid how much it costs. Then search online. Its not like information is difficult to find these days.
I mean whats another option here? Make it illegal to sell your stuff for anything above a set price?
