Gamestop Credit to Cash Ratio

[arsenalgear]

I'm thinking of trading in a ton of games to GameStop, but I have no real interest in getting credit (I'm trying to slim down my collection)---how much cash can you get? As in, if I were offered 50 bucks in credit, how much would that be equivalent to in cash?
