Are there seasonal price differences for disney merchandise at parks vs retail?

The single source supplied is a Wikipedia article about Starbucks Corporation, which does not discuss Disney, theme parks, or merchandise pricing. Because the information about Disney merchandise is absent from the verified evidence, I cannot confirm whether seasonal price differences exist for Disney products sold at parks versus retail locations. Without data on Disney pricing policies, any statement about seasonal variations would be speculative. For accurate information, consult official Disney resources, park ticketing sites, or reputable retail price comparison tools that specifically address Disney merchandise pricing across different channels.
