Bad Company 2: Would buying an american version work proper while in Europe

Just wondering since I can get BFBC2 a little bit cheaper if I buy it from a store only selling american versions, would it then fuction proper in MP in europe?

By the way can anyone recommend any download stores where its under what would be 35 Pounds/38 Euro for BFBC2

Steam and Impulse does it 2 months after release if your lucky, but that's with games that doesn't sell good.

D2D has the lowest price for downloads Amazon has the lowest in general but to ship it from the UK to Denmark would cost about 40 pounds in total

So I quess I'll just buy it on D2D
