update: appears to be all head stores.
All games in Head entertainment Meadowhall, Sheffield (on all formats) are now under £10.. the ones that arent under a tenner they are busy stickering at 9.99 as I type this.
There's an exception on Hardware and Games including hardware (scene it etc) and Rockband.. Although Rockband Solus (Xbox 360) is actually 9.99 as I bought it there this morning.
There's a large amount of stuff still in there.. I only really looked at XBOX 360 and cant remember many of the games or prices (there's a lot but nothing new obviously).. I picked up Rockband and Midnight Club LA both for 9.99, they definitely had tomb raider underworld for 7.99, PGR3, Command and Conquer 3, and Kane's Wrath for 9.99, as well as many others. (not saying these are the best deals in there.. just the one i looked at considering buying)
They have moved them to the front of the store on the wall on the left by the tills..
