They do in metro Detroit as well. I went game hunting with a buddy today and we found a lot of stuff, but everything was priced off eBay. I bought nothing... Its maddening. They all say "on eBay it sells for this" Then sell it there! God...
Every "retro" game store I've visited looks at eBay to figure out pricing. But they all do the collectard "I heard about this console yesterday!" thing and only look at
asking prices and then pick the highest one, all while ignoring condition, completeness, etc.
So a game that always sells for $10 - $20 on eBay is $550 at the local shop.
