I know this is available at 365 Games for £29.99 but that's the Asian version, which some people may not want and I've just noticed Shopto are selling the PAL version (UK/European) for £29.95 with same day dispatch via recorded delivery, which normally arrives the following day.
Some people love this game and even though I've bought every single PGR game to date and loved them, I started getting bored of the almost identical forumula, so haven't bothered getting the latest version but I'm sure this is still a top notch game as usual.
Don't forget to go through Quidco to receive 4% cashback, making it £28.75 all inclusive. :)
Also thought I'd mention that the PAL versions next lowest price is £35.93 and can be traded in shops, whereas obviously the Asian version is not accepted. :)
