NM at the Fashion Show mall has a decent selection of bags. When I visited in February Tallulah G, which also has a location at the Fashion Show Mall, claimed that they would start carrying Bal bags in the spring. I was suppose to be on their mailing list and I never heard back from them, so I don't know if they did end up ordering any.
I was at the NM-Fashion Show Mall in early April and there was a HUGE selection of B-bags. Even bigger than the NM-San Francisco's!
