I was in Sainsburys High Wycombe today and saw they were putting some games, blu-rays and dvds out on shelves. I was told to come back in half an hour when they'd be ready and found a few good PS3 deals to be had.
The ones that stuck out to me were Darksiders and God of War 3 but from the photo you can see a few other titles at similar prices.
There were a good 5 or 6 copies left of each. Not sure if this is specific to High Wycombe though.
EDIT - They also had Halo Reach for £8 but that was the only decent Xbox title I think. I didn't think to get a photo because I don't own a 360.
