Question about gamestop?

Going to gamestop today to trade in some games for Assassin's Creed II as I'm dirt poor (Shameful, I know). Going to do the trade in two specific titles and get it for $20 but still 20 bucks I don't have. So I've got some games that I don't play anymore and I'm wondering what I might get for them. Bioshock, The Force Unleashed, Guitar Hero3, Cod 3, and Rainbow Six: Vegas. I know the trade-in prices vary city to city but any general priceswill help.

Wow that's a pretty pathetic question and what's worse is that I asked it :(

I'd be surprised if you got over $15 for those games.

Use the Amazon trade in value as a guide. Bioshock $9, The Force Unleashed $9, Guitar Hero3 $.75(that is correct LOL),Cod 3 $4.50, and Rainbow Six: Vegas $2.50.
