Damn, that's cheap. Even with conversion I paid about twice as much on pre-order... and I don't think Steam offered squat for pre-order extras. Regardless, I'm still looking forward to it... and it wouldn't really be worth it to cross the pond to save a few quid.
I would not get it from steam. You want collectables ya go to the store and get it But even that shop around. Some places here are not even doing the premium one at all.
