Oh Hrae, I wasnt saying I couldnt convert, I already had at the time of the post.

I dunno the prices in England although I did have a friend from England buying me my time cards. And he was the manager of a Game store, so.... yeah, couldn't give a definite price x.x but actually, the black friday sales prices are about the same, like 4 or 5 pounds for BC, prolly 9 or 10 pounds for WOTLK. I remember seeing the advertisements on my EU launcher.

I didnt know the black friday thing happened over here, maybe the media just doesnt make such a big deal over it :s

Well since they do it for the US, they give they offer to EU as well :)

Oh you meant when buying it through the website ? I thought you meant in shops. xD
