I found some cheap items in the gift section, tried to order one and it does apply the $10 coupon towards shipping. However, on a .78 order, my tax due was a negative amount and it won't let you submit any order with a negative tax total, so you need to order several products to get your tax amount over zero when the coupon is applied. It's not a hot deal.
Their products are so overpriced, and their shipping is very high for their smallest items that the coupon doesn't result in any hot deals. If you were already going to buy a larger item getting $10 off is great, but otherwise it's not a hot deal.
