This is a great deal for one biggest titles of last year and one of the most recent releases on the PS3 and will satisfy all fans of the genre as well as speed freaks.
Shopto have the second best price at £28.99 and after that, it's PowerPlayDirect for £37.49, so £24.49 including delivery seems like a steal.
Don't forget to go through Quidco in order to receive free delivery (worth £1.49) and an additional 4% cashback, making this title just £23.51 all inclusive but if you don't have a Quidco account, use the free delivery code.
The 7% voucher unfortunately won't work with this title, as it's sectioned in as one of the special offers but it's already at a great price anyway.
Hope that helps. :)
