I have seen some great deals in the US for this game, but not in the UK. The limited edition, which is the base line is £45 ( just short of $70). The best I can find is £35 on Amazon but that is still really high for a PC game. Green Man Gaming have it for £36 with a code, which is my best option. What else is out there for us in the UK, who don't get a $40 deal from Amazon.
I managed to get Tomb Raider for £16 last week so I feel it would be a bad move to get this full price.
