How much does gamestop buy a 3rd gen ipod 8 gig?

I have the same kind of iPod touch mine has no cracks on the screen and is in good condition, im taking it to GameStop tomorrow and im gonna bring some cash to try to add to what i get and get an Xbox 360, i will let you know tomorrow how much i got for it. It says on the website about $80 depending on the condition and all that so im hoping for $100 at the most but atleast 80.
