Or simply sell stuff online, in Disney stores, or at both coasts.
I live on the west coast and only make it to WDW once every year or two, if they release a unique item my two choices are don’t get it or use a personal shopper. I refuse to pay eBay prices but have used a personal shopper for years that takes pre-orders and charges retail, their profit comes from their AP discount, not saying who but Disney must know, judging by their webpage they must buy hundreds of items every month.
This is a problem that Disney knowingly created to create demand, offer a limited supply and people will buy it now so they don’t miss out. That demand also created a demand for personal shoppers and eBayers.
