I bought a pre-owned PS2 from Gamestop along with the 1-year warranty over the summer (July).
I want to buy myself a PS3 over the holidays (for the PS3 exclusive games) so I figured the extra money will help.

Is there any way I can return or exchange the PS2 for store credit or at least partial credit? Perhaps return it under the warranty and ask for store credit instead of another system?

Most suggestions are appreciated. Thanks!
