In what seems like an effort to keep Frozen merchandise in stock, all of the domestic Disney theme parks are now placing a purchase quantity restriction on Frozen merchandise.
Beginning yesterday, all Frozen products have a purchase limit of five. This means that you can purchase up to a maximum of 5 of the exact same item. You could for example, buy 5 Elsa dolls, and 5 Anna dolls, but not 6 Elsa dolls.
The restriction has been but in place at all the domestic properties, which includes Walt Disney World, Disneyland Resort, Disney Cruise Line, and Disney Vacation Club locations.
