with it being announced that the game had gone gold yesterday and a final release date most likely due today it seems the definitive racing game is FINALLY on its way and at this price who can refuse :D
enter codes MS-EXPERT-XMAS (Thanks to hsg) and MCMEXPOST (Thanks to Reser) to receive £6 credit
Those two codes (as of Tues 2nd) only work for new customers. So if you've shopped with Shopto before then they won't work. You could try setting up a new account with a different email etc...
