This was most likely a pricematch for play.com sale of the same guide for £7.99. Seems the price on play.com has since risen to £14.99.
Still available from amazon.co.uk for discounted price.
Seems like a good deal for the collectors edition of the guide for a good game. And yes, I know you can get the game now for a bit more than the guide but should go well if you are a fan of the game. (see http://www.hotukdeals.com/visit?m=51&q=718945)
