Game.co.uk just slashed the price of this to £19.99 including free delivery. According to Find-games (http://www.find-games.co.uk/ps3/B002KCO728.htm) the next best is £27.85.
Don't forget, Quidco, Topcashback, etc., give 6% for Game. *Also, members will get back 2.5% as a Reward* :-)
PS I've marked this as Online only because I have no idea what the in store price is, and my experience of Game is that generally there is a significant difference
