Sometimes you can get lucky with bags, I bought a Marc Jacobs there once. The ones I go to always have the good stuff locked in a display case. They have their own Barney's brand bags and wallets out on the floor.
They always have jeans (I see Seven, True Religion, etc), seasonal items (cashmere in the fall, dresses in the spring), shoes, etc. The ones I've been to are relatively small stores.
