When you trade in a 120GB/160GB/320GB PS3 or a 250GB Xbox 360.
GAME will be offering the 500GB PS3 with or without FIFA 13 for half price when trading-in a selected console, the retailer has announced on its website.
The solus and bundled systems are both priced £249.99 on the GAME website, meaning you'll be paying £124.99 if you take up the trade-in deal.
The best value option is getting rid of an old 120GB PS3, but the deal also works with the 160GB PS3, 320GB PS3 and the 250GB Xbox 360.
The offer runs from September 28 through to October 12 and only while stocks last.
An upgrade from an ageing 120GB PS3 to the 500GB plus a copy of FIFA 13 for £125 doesn't seem like too bad a proposition.
