Yes you can trade a DSi for a DS Lite at Gamestop.
GameStop will give you about $4.00 for the ds lite dame you are sending.
It depends on the store your selling to. You will not get much from game stop. I'm selling my ds lite, and a bunch of games and they'll only give me $50. and if you are 17 or under, they can only give you store credit, like a gift card to gamestop, not real money.
