If I were to make a trade-in at Gamestop, how much money would I get if I put it all on an EDGE card?

In my opinion, selling stuff to GameStop is a rip off. They gave me $0.78 for a game I sold once. You'd probably get more money if you sold all your stuff online or somewhere other than GameStop. But you'd probably get maybe a little more than $120 if you sold your stuff there, but I'm not completely sure.
