Not sure if I have posted this in right section but just incase useful to someone they have reduced xbox, ds, pc, a few psp and ps3 games in the above store.
You won't find them upstairs in the entertainment section but they are downstairs in an aisle between the normal grocery aisles.
I'm not sure what is left now but they had loads when I went Monday so worth popping in if passing.
Xbox Games were mainly from £8 up, pc games £1, ds games from £4, Wii from £6.
A few prices for xbox 360 were guitar hero world tour £14, race pro £12, Dirt £10, Baja £10, Mortal Kombat £10, Grid £10, Sonic unleashed £10, Bee movie, Smackdown 2009, viva pinata, Juiced 2, Stuntman ignition, Pro street, too many to list.
