Pre-order Call Of duty Black Ops premium pack on Ps3 and Xbox 360 in Asda for £5 deposit. Advert states Maximum price you will pay is £44.97 but the actual price on day of release may be cheaper.
Pack includes the game itself plus you get a free t shirt and strategy guide (brady games signature series guides).
Chances are Asda will prob do this cheaper than the stated price on the day but with the free t shirt and guide i think this is a pretty good deal anyway.
If you find a better deal somewhere else you are perfectly entitled to go in and get your £5 deposit back so really you can't lose.
