Beekman Blaak Serum and Night Cream Duo Price Difference?

If HSN and QVC are owned by the same company and HSN is the home of Beekman why is there such a price difference on this product? QVC has a normal price of $66 and is selling it for $60. HSN has a normal price of $99 and is selling for $84.95. It’s the same products as far as I can tell. What’s going on?
