Gamestop Trade In Value for these games(educated guesses)?

I'm hoping to trade in some games to obtain Madden 12 and perhaps preorder or buy another game, here are the games I'm trading in.





Homefront Xbox 360

Call of Duty Black Ops Xbox 360

Nintendo Gameboy Color Advance SP

Pokemon Diamond

Kirby Amazing Mirror(I think that's what it is)

Mario Luigi Partners in Time







A good guess would be much appreciated. Thanks. :)Gamestop Trade In Value for these games(educated guesses)?
I don't think they will buy the Gameboy Advance any longer. About a year ago they said they would no longer buy the gameboy advance games.



I would take them to a pawn shop and see what they would give you. I bet they would give you more money for them than gamestop.



Honestly I can not see you getting over $30 for all of that excluding the Gameboy. I inquired about selling PS2 games and they said that they buy back some of them for as low as $.25.Gamestop Trade In Value for these games(educated guesses)?
Homefront - 20-30$

Black Ops - 15-20$ Maybe

Nintendo DS - atleast 40-60$ I would think

Pokemon Diamond - 2-5$ Maybe

Other two games like - 2-3$ piece maybe.

With lowest prices 81$

With highest prices 121$

30 to 40 dollars I would say... gamestop really rips people off with trade ins lol.... black ops should definitely get you decent money
