The huge Pottery Barn Outlet Store in Jeffersonville, OH is my favorite part of the Prime Outlet mall there. Sure, saving thirty to forty percent on clothing may be nice (at other stores), but at Pottery Barn you're buying huge pieces of furniture, and so the savings are much higher. Forty percent off of a two thousand dollar bed is worth traveling for!
The Prime Outlet Mall, with the Pottery Barn outlet store, is easy to get to - take I-71 (and Highway 35) to exit 65 at the Xenia Washington Court House.
My favorite part about the mall, in general? It's built in the new style, so instead of just a strip mall, you can walk around outside, wandering through the whole place, window-shopping and going into the stores only when you feel like it.
