Basically, GameStop is no longer getting trade ins for Gamecube! So if you want to get some GameCube stuff, better go out and buy it all since when its gone, its gone for good. They will sell what they have left, they don't care what happens but they want it gone now. RIP GAMECUBE! The actual Reason: Sadly, I can't find one! Get some cheap games for GameCube now before its to late!
Just FYI... Play'n'Trade (in my area, at least) still deals in Gamecube stuff. Heck, they carry some NES and 2600 stuff. I don't know if they still take trades, actually, but they definitely still stock lots of stuff.
I already got all the games I wanted for the Gamecube while it was a big hit. Don't think I'll go back to it anytime soon. If anything I still got eBay. =p Also the Play'n'Trade in my area turned into a sub shop now. =/
