Mass Effect is a critically acclaimed RPG game for PC and Xbox 360, currently selling on Amazon for £12.20. The game is available on EA's own store for £9.99 and by using a coupon this can be taken down to £7.49. You don't have to wait for this game to arrive - when you buy you start downloading it directly to your PC so this is not suitable for those with limited internet connections.
This price can be acheived by using the 25% off voucher that I have added to HUKD at http://www.hotukdeals.com/item/478947/25-off-purchases-at-ea-store.
Just add the game to your basket and then enter the detailed code into the basket screen.
There is also the possibility of gettting another 10% off of the price by going through Quidco, as they offer 10% on EA Store transactions.
