Also, please remember that if you somehow manage to find a physical version of the full collectors edition in some store you will not be able to use the registration code on your currently active account. The registration code within the collectors edition game (not the upgrade) is only of use to "new" accounts so purchasing one for the free 30 days would be a waste as you cant use them.

The collectors edition upgrade from the Mog station gives you the items and works fine with an active account.
