The great thing about Shopto is there fast delivery method, as the site states that all orders completed before 5:30pm will be dispatched the same day and 99% of the time will arrive the next morning, which has happened for me every time i've ordered.
The brilliant Forza 2 limited edition is now available for just £38.99 and the next cheapest instock price is £41.64 from Tesco but they're quite bad with there deliveries and the next cheapest place is £45.
I have the standard version of this game and i have to say, the great reviews it's received of around 93% is well and truly justified and it has many great innovative features, such as auctioning cars you've earned to sell on online and much much more.
Don't forget to go through Quidco to receive 4% cashback, which makes it £37.43 including recorded delivery.
Hope this helps. :)
