I have noticed in the past others have voiced a shared frustration with the HSN website. Just an FYI I requested on COMMUNITY CUSTOMER SERVICE:

I have a suggestion to improve your website. This improvement would speed up the online shopping experience and decrease customer frustrations. Amazon has this option when browsing lists of items. Please add the option to display only items that are currently in stock. Below I have displayed how Amazon provides the option to customers. If the customer x’s the box, they display currently out of stock items.
Thx.

AMAZON:
