What is the difference between disney world exclusive and disney merchandise?

The only verified information available comes from the Wikipedia entry on the film Wish, which discusses its production, plot and cast. There is no mention in that source of Disney World exclusive items or of Disney merchandise in general. Consequently, no factual basis exists within the supplied evidence to explain the distinction between Disney World exclusives and regular Disney merchandise. For accurate details on Disney product lines, official Disney retail or park websites would need to be consulted.
