Right now on the HSN site, all Nyx sets are on sale with FREE SHIPPING. Plus, there are lots of different codes right now that you can try to use with your order for even more savings.
These are some nice deals--for example, the 6-piece Soft Matte Lip Cream Set (click here for my review of one of the Soft Matte Lip Creams) is $20.95 + free shipping. The Soft Matte Lip Creams retail for $6 each on the Nyx site, so you're saving $15.05 with this HSN deal.
I wouldn't wait though, because I having a feeling these will sell out quickly.
