Please give me an estimate to how much trade in credit I would recieve from these video game items at Gamestop?

I would really like to get a PS3 and I have tried craigslist for a while but I have gotten terrible offers or no offers at all. Currently, I am a part of Gamestop's Power Rewards Pro program and I have a coupon that gives me 40% more trade in credit than I would usually receive on all of these game (so please keep that in mind).

Please try to give me an estimate. No answers telling me to go check for myself please. I would really like to have an idea before I go and trade these in.Please give me an estimate to how much trade in credit I would recieve from these video game items at Gamestop?
Never trade in at gamestop. I had tons of new ps2 games with huge value and Gamestop ripped me off. Maybe it was dumb blondie that looked like Mary Jane from spiderman 1 and 2 that messed up tons of errors for me. And all I did was trade in my awesome games for a crappy 512mb with 2 32mbs that I STILL HAD TO PAY WITH MY OWN MONEY!!! If I had a time machine I would go back to the past and slap myself for doing such a thing. Also I left a white 8mb ps2 memory card in the Naruto case. So my advice is NEVER TRADE IN AT GAMERIPSTOP.Please give me an estimate to how much trade in credit I would recieve from these video game items at Gamestop?
its about 1-3 dollars a game. oh wait, if you have the coupon 60-70. probably less though.
