I have another resource:
www.shopnational.com. It's National Wholesale out of Lexington, NC. They send out frequent catalogs and you should be able to sign up for their mailing list at the website. I used to buy some of my Mom's clothes from them. They have a lot of basic things that are pretty nice. Their prices are along the same lines as Blair's.
I've ordered things from most of the places mentioned above, too... Haband, Woman Within, Roamans, Boscov's, etc.
