HSN cuts $20 off orders of $40 or more when you pay with Visa Checkout. (The discount will be automatically applied after you've signed into your Visa Checkout account.) That's one of the best general-use dollar-off discount we've seen from HSN, although in June we saw $25 off orders of $50 or more. Shipping starts at $3.95, although select items receive free shipping. Some exclusions apply. Deal ends September 19.

Note: This discount can only be used once per account.
