I have attended two events through D23 and was not lucky enough to have any D23 merchandise available at them. Seems like that might only be reserved for West Coast events?
I am really hoping to get a complete set of the Epcot patches if they are made available. If anyone attending the upcoming events or tours is able to pick up some extra sets, please let me know. In any case, I would be interested to know if they even make them available, although I really wish they could find a way to make the complete sets available without having to attend the events.
