You never get too much unless it's a brand new game Even then not that much
They not gonna give you that much its better trade them in Facebook or other page
It depends on the demand for the game. However, if you had the newest, hottest game that cost $60 they'd give you maybe $15-$20. Maybe. And, whatever you do don't trust their online information. You'll get to the store and they'll tell you it's not worth that at their particular store. Truth. It's happened to me there with Monster Hunter World. Not hating on the people, but it's the chain's M.O.
Depending on the game, probably not more than a few dollars each.
