A special deal went on today, and Assassin's Creed is now only £29.99 on Xbox 360 and PS3, so make sure to pick it up now if you haven't already.
This is online and offline so if you're buying it online don't forget to use quidco (11%) and one of the vouchers if you spend a little more, an example of the cheapest thing would be the gift wrap (99p), so that way you still save money :)
So in the end you'd be paying (if using vouchers and quidco) about £23.13 (not exact)
And don't forget to use your points card, you'll get 310 points which is worth about 78p.
And if you're buying it in store don't forget to use your loyalty card as well :)
