Was in Huntingdon today and decided to pop in to Curry's to see if they had any good deals going on and they did. DiRT 2 was selling for £10 in Curry's not long ago and that was a good deal so when I saw it for £4.97 today I knew I had a bargain on my hands. I was given the game brand new with seal and then went round the corner to GAME to trade in for £8 credit!
Army of Two the 40th Day was also £4.97 and I picked that up myself to keep and play (although this isn't brand new). I've scanned in the receipts for proof of purchase. I'm not sure if these prices are nationwide but I did just check on their website and DiRT 2 is listed at £4.97 just not in stock.
Also worth mentioning that Operation FlashpointL Dragon Rising was also £4.97 as was Vancouver 2010. Mass Effect 2 for £9.97 also seemed like a good deal. I know this has been posted before but I thought it was worth another mention for anybody interested.
I had a quick check for the PS3 but didn't see the games there at the same price.
