I think this is for canada only but if you trade any PS3, Xbox 360, WiiU, PS Vita or Nintendo 3DS game and get Battlefield 3, Assassins Creed 4 or CoD Ghosts for free but you can only trade games towards current gen versions of these games but you could probably upgrade it for 10 dollars essentially paying 10 dollars for a next gen game. The deal goes on from the 9th to the 11th of november.
