Right now the Home Shopping Network is offering $20 off one items of $40 or more with coupon code 128306. If you've had your eye on something this may be worth trying out. Shipping starts at $4.95 but several items do qualify for Free Shipping.
You can not enter your code until the final process before payment is submitted. Keep in mind some items won't apply. I just tried the Daily Deal Offer and it doesn't qualify (which I didn't think it would).
