Gamestation have a classic deal that comes and goes. The reason why this is so great is that they'll accept the games back and trade against the original cost of the console. Fallout 3 and Fable 2 together get £47 meaning that you'll get an Elite console WITH extra controller for £192.
They didn't have any Fable 2 games in Croydon so they gave me a further £5 and gave me a preowned game (which was traded as above).
This deal is obviously in store as you can't trade your games online.
