A gamecube costs 20 dollars at gamestop
$10
at gamestop they are 29.99.
it depends on which game it is
10-40 dollars, it depends on the the condition it is in and what Gamestop you go to.
About 12.00 USD store credit. GameCube is now an outcast, kicked out by the Wii.
3 to 4 dollars
Not enough. If you have a local game store, that store will normally give you at least a little more than GameStop. My local game store will give you $10 just for a GameCube Controller were as GameStop will only give you ~$12 for the fully working system, controller, and memory cards. I know from experience
Most GameCube games retail these days for between $20-40 at places like GameStop.
Probably a litle over $100
for gamecube it is about $10-$20 but gamestop has it cheapest
