Still a little confused by what type store you mean.
There is not a Sephora in Savannah. We do have an Ulta which is similar but smaller. The fact that they have Kenzos when nothing else in the area does makes those the best there.
We have B-grade dept stores of Macy*s, Belk, and Dillard's. They carry only the most likely to sell frags which around here are the trendy and newer ones. Belk does carry Boucherons and Thierry Mugler though.
Then there are the true discount spots TJMaxx/ Marshall's with their usual hit or miss deliveries that can produce an amazing find from time to time, usually in the form of a Guerlain or YSL. Perfumania has the widest selection and that makes them "the best" for an actual frag outing. They have a couple of Annick Goutals, Cartiers, and the like on a regular basis, so they aren't completely without a higher-end/quality presence.
