One of my favorite stores in Madison. I usually don't care for soapy boutiques, as they tend to be overpriced and, I dunno, too whoosh for me. This happy place keeps me from having to mess around with any other ones.
The best deals here are the custom soaps they mix up for you in the store. You select a big, medium, or small bottle of unscented body shampoo, bubble bath or whatever, then pick a scent from about a hundred little bottles of natural fragrances. They mix in up to your specifications, let you take a whiff, and sell it to you at a very reasonable price.
I keep seeing the same people there year after year. Every single time the staff has been friendly and has known their stuff.
