As of October 2014, GameStop pays $60 for the system hardware of a 320-GB Xbox 360 in good condition. A seller can earn additional money by bringing in cables, controllers, adapters and games for the gaming console. Prices do fluctuate, so it is important to check with your local GameStop for the most recent trade-in values.
When GameStop agrees to purchase a gaming console or accessory, the seller can choose to receive the trade-in value in the form of cash or a store credit. For a small fee, GameStop shoppers can enroll in a program called PowerUp Rewards PRO. PRO members earn the same price as non-members for the Xbox 360 hardware, but they receive a higher trade-in value for Xbox accessories and games.
