No clue! Are you in a guild? If so, post to your guild asking if anyone has a spare. My hubby and his friend are going, leaving me home with the kids to play WoW alone.
Anyhow, if you're not in a guild, perhaps I could post on the boards of ours to see if anyone has a spare they could sell ya.
Also, if you haven't already, try ebay.
Good luck!!!!!
