I know a majority of my friends love Gilt.com, but I never ever hear anyone talk about Hautelook. So if you don't know about it, listen up! I discovered the site even before I was a member of Gilt and love it. Basically the same idea as Gilt and sells a variety of products from clothing jewelry and accessories as well as beauty products and home goods. Another favorite of mine is Ideeli whose website layout I hate but has some good sales as well. See below for invite links!
