They are sister stores (the same store). Premier is the newest and had a good collection of WDW items, from clothes to houseware. The last time I was at Belz, they had 2 stores, one carried more clothing than the other. I would head to the closest store (Premier) first to see what you can find. It is hit or miss and I've found some of the same stuff in the WOD store and park & resort stores also discounted at the same price. But did find more "hardgoods" at the outlet.
