ASDA has the following PS3 games on sale
Motorstorm 2 £24
Bioshock £14
Soul Caliber 4 £14
Bad Company £15
There were several others (Mirrors Edge, GTAIV and some more) but I cannot remember the prices for all of them, only the 3 above as they were the ones that I was interested in. I ended up buying Motorstorm 2 and Bioshock.
