Ask for the store manager. He is much more knowledgable than the other employees, and he also has more access to insurance information. I really wish that I had just asked for him earlier because I waited around for over 45 minutes just so the employees could tell me that I was "no longer covered under my parents"...which the manager (with a quick search on his computer) found otherwise.
The selection at Stanton is limited (especially if you are looking for name brand frames), but I was able to find a few that I really liked and fit my face well. I'd suggest going to LensCrafters if you have in-network insurance, because the selection is much more inclusive there. But if you have VSP like I do, Stanton is a great alternative as long as you don't mind doing some hunting!
I can't wait to wear my new glasses. B)
