We really didn't buy as much as we had anticipated -- especially since we did nearly all of our Christmas shopping either at WDW or the Disney Warehouse.
The 3 kids all got winter hats. The two younger ones got the Mickey and Minnie Christmas hats. (Cute photos!!!)
Christmas ornaments were on sale, so we bought the Mickey head-shaped ones for our resort tree. These were super-cheap at the Warehouse.
I really don't remember much out of the ordinary being offered at Christmas other than ornaments, tree skirts, stockings, and a very few Christmas-themed shirts.
