Traded in 15 (!) games at GameStop in order to pay-off Halo Reach ($60) and get $33 in store credit. Halo 3 brought in the most at $8, while Guitar Hero Aerosmith got me $0.35, or 1/100th of what I originally paid for it, and that's with a 40% bonus. God fucking damn it. Next time I'm selling my used games on Ebay.
