Was in HMV in Ipswich today and opposite where their wii ans ds games were they had a stand full of reduced games on all formats. I don't know how good the prices on PS3 or Xbox were but several were around £10.
On wii I got geometry wars galaxies for £4 (cheapest in stock online is £8.95) and they had several other games under £12.
On DS they had big bang mini for £10, Ellen Whittaker's horse life for £8, Jamie Oliver for £8 2 different final fantasy games at £10 each and several others which I can't remember!!!
Also had a few bits and pieces like wii table tennis bats and rock band drum sticks @ £4 each and guitar hero stylus @ £3.
Worth a look if your whsmith has sold out of everything like ours has!!!
