In a move that will frustrate collectors outside of the US, it has been announced that the Original Trilogy C-3PO Black Series 6" figure will be a Walgreens exclusive. The Force Awakens version will be arriving later this Autumn in Wave 8. This version, without the red arm and complete with Silver Leg, will hit Walgreens stores by the end of the year.
The issue with this, outside the US, is that any previous Walgreens exclusives have not made it easily to UK stores and have instead been imported at a huge mark up vs a standard figure. For now we await full details.
