Where can i buy authentic disney world exclusive toy story items?

The only verified facts we have are about the Toy Story franchise and the Little People toy line produced by Fisher‑Price and Mattel. There is no mention of Disney World exclusive Toy Story merchandise or authorized retailers in these sources. Therefore, I cannot confirm a specific location where such authentic items can be bought. You may want to consult the official Disney store or Disney World gift shops for official merchandise, but that is not supported by the evidence given.
