Word of warning, it just struck me to check and sure enough CD Wow is a UK company, and other Blizzard games (WoW, Starcraft 2) are the UK/EU versions, which cannot be played with/against US players because Blizzard is the devil. Trying to cancel my order now and get a refund, I'll post on how smoothly that goes. Bummer.
Edit: Great service. Sent the request to cancel my order last night, got a full refund today. Not shabby at all considering it's the weekend.
