Blood Bowl for the PC is priced at £11.99 with free delivery from Play.com right now. A price comparison shows me that the next best online price is £17.99 @ Tesco, so quite a difference.
I stumbled across this game when I was price comparing another, but I think it is a good deal. I've not actually played it, but you could google for reviews if you would like to know a little bit more. Gamespot gives this a 7/10 which isn't bad.
