This offer starts tomorrow, November 9th, and runs until Monday, November 11th and is for Canadian gamers only.
Future Shop has confirmed that this is a legitimate offer on their community website, with the following stipulations:
Just remeber that the games you trade in need to include the cases, and no duplicates. Again, this deal is Canada only–sorry, rest of the world.
Trade ANY one game on Xbox 360, PlayStation 3, WiiU, PS Vita or Nintendo 3DS and get a FREE copy of Assassin’s Creed IV, Battlefield 4 or Call of Duty: Ghosts (Xbox 360, PS3 WiiU versions only, excludes next generation consoles - PlayStation 4 and Xbox One. Regular $59. 99 versions only). That’s right, bring-in any game title on the present-gen console or handheld and you get one of three of the holiday’s hottest titles for free. Limit one title per customer per day - games must include cases - and no duplicates accepted. Of course there some legal limitations in some markets. Future Shop stores in Nanaimo, Kelowna, Manitoba, Vaughan and Richmond Hill are excluded due to local trade in laws.
