Buy a couple used copies of Stranglehold at GameStop (either PS3 or the 360 CE--must be CE for 360 version), trade them into Blockbuster then use the BB/Game Rush thread to pick out some games from Blockbuster to trade back into Game Stop for credit transfer. You'll get about $70-75 in credit at GS for a total of about $35 and hopefully not too much gas between stores.
