I just used the BE web site to find locations. I imagine their own boutiques are best for getting trained help.
DH saw an ad in our newspaper which said a local beauty shop is selling BE! When I called to check it out, they said they were only allowed to sell some items.
In the BE store in Atlanta, they gave me 3 samples of my choice with purchase. However, when I was at their store in the Atlanta airport some months later, they said they weren't doing that any more. It's worth asking....I got some really nice eye shadows.
