It's a pre order (due out on 8th April) but this is the cheapest I can find it anywhere. It's around £10 more expensive in most places, other than Bee.com which has the game available now for £17.99. I'm tempted myself!
God of War III is a single player action game, exclusive to the PlayStation 3, and the final installment of the God of War trilogy. Containing signature and addictive God of War gameplay a combination of over-the-top action combat, exploration and puzzle-solving along with an engrossing mythologically inspired storyline and a selection of new weapons and a new weapons system, it is a fitting conclusion to the much praised God of War franchise. True to the series roots, the four pillars of game play - brutal combat, intricate puzzles, exploration of awe-inspiring worlds, and a compelling story - all return. God of War III is the epic conclusion to the Greek mythological trilogy, which will complete Kratos' story that began in the original title for the PlayStation 2
