I traded a dude the boxed WOW Buring Crusades for the D3 Collectors edition, went to Bliz and entered the key code, and poof, Inarius Wings of Justice. Not to mention a Diablo Skull and USB Soulstone with a whopping 4GB flash drive. Good trade. They are out there if you want it.
Also Big props to MissCheetah list of [List of all Wings, Cosmetics, Pets, and Promos.
