depends on how NEW the games are :)
It depends what the games are and each Gamestop varies. Call your local Gamestop and ask.
I wouldn't recommend going to Future Shop. Go to EB Games or Gamestop and if you trade in 3 games you get one game for free!
go find out but probaly round 45-50 dollars
$20
$2
about 20$ for the sp and 3-4 for the games not sure about the case
$120.00
3 to 4 dollars
30 to 45 bucks
Gamestop will give you either 1/3 or 1/2 of the price depending on the condition of the Xbox.
If you trade it with GameStop, they may offer you approximately 5 dollars for it. Correction: They might give $7 - $10 for it...
About 3-5 dollars if you're selling them to Gamestop.
