Not for everyone but I'm a massive fan of these SNK series.
King of Fighters XII for either Xbox 360 or Playstation 3 for £14.99 on Gamestation's website - this is by far the cheapest price for this game anywhere! This game isn't the easiest to track down with many retailers not stocking it. If you're a beat em up/SNK fan then this is a good deal!
Next cheapest appears to be CoolShop at a staggering £29.50!!
Have no idea what the price is instore.
Quidco for 6% as well.
