Witcher 2 going cheap on Steam

The Witcher 2: Assassins of Kings Digital Premium Edition is currently going for 40% through Steam, making it £15.99 (usually £25.99).
You’ll need to be quick though as the offer ends today (Thursday 15 Dec) at 4pm PST / midnight GMT. 
If you’re yet to play it then you really should, in his 9/10 review Tim describes it as “brain-searingly spectacular…not just in a visual sense, I’m referring to the vision and the execution.”
