Just seen this article on T3 saying you'll be able to pick up a copy of Grand Tourismo 5 for £7.47 if you trade in either
-- Assassin’s Creed Brotherhood or
-- Need for Speed: Hot Pursuit or
-- Star Wars Force Unleashed 2
"Gamers looking to make use of the sub-£8 Gran Turismo 5 deal, an offer which will run for 11 days following launch until Saturday December 4th, will have to trade in a copy of either Assassin’s Creed Brotherhood, Need for Speed: Hot Pursuit or Star Wars Force Unleashed 2. Customers looking to pick up a copy of the game on its own will have to fork out £39.47."
May not be as good as the HMV offer (trade in F1 get game for £3.99) but if you have one of the above titles this might be a better deal for you.http://www.t3.com/news/gran-turismo-5-release-price-just-%C2%A37-47-at-asda?=51171
