Hi ya just got back from Morrisons in norwich and they had Guitar Hero on the PS3 the Metallica version and Greatest hits version (both solus). for just £26.99 each which i think is a good price as these tend to stay around the £35-£40 on the PS3.
sorry dont know if they had it on 360 didnt think to look as we dont have an XBOX
This should hopefully be nationwide as they were properly printed up shelf label and the games where in the chart shelves not bargain bins, so this should be a proper deal rather than stock clearance.
hope this helps another fellow GH addict.
