This game is supposed to be better than the GT Pro Series deal i posted earlier and is a similar package, as it also comes with the steering wheel.
This game is now available for the discounted price of £24.99 including delivery and if you go through Quidco, they're currently offering 11% cashback, making this just £22.24 inclusive.
Hope that helps. :)
This seems to be the lowest price by at least £5 and has a very high cashback rate.
