Popped into WH Smiths in Newcastle-under-lyme today for a bit of a browse, and noticed they'd moved all the PS3 and XBox 360 games off the wall they were normally on, and onto a seperate stand. All the games they had on there were reduced. The ones i remember seeing :
COD4: Modern Warfare (Not 2) : £14
Dead Space : £9
Street Fighter 4 : £19
Mercenaries 2 : £9
Singstar Abba : £14
I didn't look to closely as i've bought too many games recently so knew i'd be to tempted if i kept looking, but there were quite a few different games for both formats, at least 20 i'd say.
Don't think it'll be individual store only, as they had a special sale shelf edge thingy across all of it. I'd be interested to hear if others have seen something similar in their WH Smiths!
