On a side note, there are several people on eBay selling used WoW games. Sanity check here but aren't those useless if the CD key has already been used?

This one is crazy:

"Item is used. However everything is included, discs, guides, manual, passes for friends. The one month free time is no longer available. However I do believe the friends passes are still good. Discs are in excellent condition. No scratches. As is item"

Sadly, I'm sure some unsuspecting soul will purchase this.
