A week or so ago, Gamestop introduced a promotional campaign that would allow PowerUp members to upgrade certain Xbox 360 titles to their Xbox One equivalents for only $9.99. Well, Amazon must've thought that was a pretty good idea, because it just unveiled a trade-in offer of its own. The promotion only applies to certain titles such as Call of Duty: Ghosts, Assassin's Creed 4: Black Flag, FIFA 14, Battlefield 4, NBA 2K14, Watch Dogs, Madden NFL 25 and Need for Speed Rivals. Simply ship the Xbox 360 version of the game to Amazon to be approved, and you'll get a $25 bonus credit on top of the title's trade-in value of at least $25.
Bear in mind that the promotion can only be used once. If multiple games are selected, the discount is for the cheapest item only -- the credit will be applied automatically upon checkout. Of course, if you simply waited until November to get the next-gen console along with the next-gen game, you'll save $10. But we know some people just can't resist the latest and greatest of multiplayer first-person shooters. If you're keen on taking advantage of the offer, you had better do it before December 31st however, as that's when it expires.
