I read the last few pages. I think most of you know about The Avenue, Lane Bryant, Cato's, and Fashion Bug. If not, here are the links:
Lane Bryant (provide your email address and you'll receive lots of coupons)
Fashion Bug Cato (no online shopping but you can use the store locator)
Torrid(They regularly slash 50% extra off their already clearance priced items so check often!)
Silhouettes Roaman
Lane Bryant Catalog is now closed and was a completely different company than Lane Bryant. I never liked their clothes anyway.
Curvy Girl Catherines b & lu Big Gals Lingerie (custom lingerie for ANY size)
Monif C Igigi Swak Designs Plus Size Bridal Avenue
Jessica London (is now paired up with Avenue so follow its link)
Rainbow (check the store locator and make sure you select 'Plus' as the department)
Old Navy (I think their Plus Sized fashions are only available online)
Woman Within Alight Maximum Woman
