When you trade in Fifa 09. Not got Fifa 09? Ok, just use the one they give you free with it for £15 cash back or £25 credit! I actually used the £25 and got 5 for £25, inc PGR3, Ghost Recon, King Kong, Sega Rally and Splinter Cell DA - a console and library for £130!
I know some prefer the 60gb one but this is dirt cheap and a good outlay for a kid's present where the rest of the relatives buy the games.
Didn't see the PGR4/Halo Bundle :(
