The Tartetlette Amazonian Clay Matte Eyeshadow Palette alone retails for $44 at Sephora. Right now (and through 1/31) on the QVC website, you can get both the palette and the brush you see above for a grand total of $42.08 shipped ($36.36 + $5.72 shipping). Not a huge cost savings but, again, you do get this double-ended brush which I believe is exclusive to QVC.
If you've been wanting this palette, this might be a nice way to save a tiny bit on it, and get a brush for free!
PS: Laura over at My Newest Addiction has a great review of this palette with swatches HERE, if you'd like a closer look.
