I think it can be hit or miss at either location. Sometimes my family and I have found great items at the location in the Premium Outlet Mall and other times we did not get anything.
As for the location at the Prime Outlets on International Drive we have only been there once which was last December and I was able to purchase a lot of new pins that were on sale. Besides that my parents got some things for themselves, however when we are back there in a few weeks we might not get anything.
