w0000000t! Another WoW player!
The games are actually much more expensive in Europe. We pay €60 for a new game, which is $80!!!!!!! It's just sick, compared to 'your' $50.
We just happened to have a cheap (€7,50) duo pack of the expansions. The normal game was already €6 for quite a while.
Oh well, you'll find a cheap version one day.
Until then, have much fun with WoW!
