How much will gamestop give me in store credit for this and then how much will the 40 gig ps3 will cost wit it

you will get about 5 dollars for each game so all your games would be worth 40 dollars and to buy a new ps3 for 400 dollars you would still need 360 dollars plus tax. for a fat ps2 they will give you 4o dollars for it but you need a controller and for the memory card they will give you 8 dollars so you will have 88 dollars in store credit so you will need 312 dollars to get a 40gb ps3.
