Happy shopping!
Yes, there is a store. However, I did find all the stuff in the parks and the hotel stores. Just not all in one place. The store isn't very big. I did buy a bunch of stuff there though... Here are some pictures I took of the place. There was probably only 5 racks of stuff plus two racks out in the aisle.
