When the Gilt Groupe created their online, invitation-only sample sale Web site, women around the world rejoiced. Now, anybody with an iPhone can join the exclusive ranks, Rebecca Bloomwood-wannabes included (protagonist of the "Shopaholic" novels), just by downloading the free app, Gilt on the Go. 

The snazzy feature of this free-sample app is the sales alerts, so you can be the first to know about the 36-hour sale with 70 percent off Oscar de la Renta shoes or moisturizers by MD Skincare. No matter where you are, you can pick up the latest designer finds at a fraction of the retail price.

Personally this app makes me miss the thrill of the hunt, but it is perfect for finding your must-wanted item without waiting in line for hours to find the perfect heel at a great price.

Once you sign up, refer your shopaholic yet economical friends and receive a $25 credit when your friend makes her first Gilt-free purchase.
