I don't even think you can buy tickets in London, either. Sounds completely sold out. May have to see if you can buy a package deal over there through different tour companies. I've been trying, no luck. It's a pretty big deal over there.
I've just listed my tickets on eBay, if you want to bid, search "NHL London" for them. My name on eBay is Kimi301388, The lot numbers are 270152431621 for the Sat game and 270152437572 for the Sun game. Searching for them on eBay should take to right to my tickets. (please give me money... I'm a student so I really in debt... lol)
@Mods: sorry if I can't post this, if I can't then people can PM me for the links/lot codes
