How much does Gamestop give for a used Wii and a used Xbox 360?

Whereas buy back value might be lower, trade-in value might be a lot better. Gamestop always offers special discounts toward certain purchases and whatnot upon a trade-in.

Definitely call, and try to haggle in a free membership or something. It gives 5 or 10% off used game purchases.
