Gamestation have got a bit mixed up with their promotions again.
PES is currently half price when bought with any new game. Up until 5 mins ago the cheapest new title was Football Manager for £4.98 but I got the last one of those. As an alternative Splinter Cell is excellent value at £12.98 and there are others at decent prices also such as Bullet Witch at £14.98.
They are also offering the Venom remote free with any new game so add one of those also FOC. You need to follow the 'Special Offer' links below each of the items to obtain the discounts.
5% Quidco also
