I agree mostly with @paulabugs. I find her shows frequently listed in the program guide when I check QVC/QVC2(non repeat). I don't find her attractive or entertaining. Her clothing items are overpriced. I don't watch any of her shows with beauty or home related items. I am only able to tolerate her for a minute or two.
I assume she is holding QVC up financially with her heavy rotation and she wouldn't be continually on if consumers weren't buying her products.
