A 3DS cost $249.99, GameStop will give you about $150, but Best buy will pay you full price probably. Best buy is way better. GameStop is a rip off. It's good to buy things from GameStop but Not sell it to them
I think GameStop or Best Buy will give you $170. Nintendo 3DS comes with a new way to play, 3D with no need for special glasses and the 3D Depth Slider allows you to find out how much 3D you want to see.
