The newest site to host flash sales is one you're familiar with already—Amazon.com! The company launched Myhabit.com today—a members-only site similar to Gilt Groupe and Rue La La. Membership is free, and those who sign up will have access to 60 percent off men's, women's and children's clothing, as well as jewelry, accessories, and footwear. The site is expected to run four to six sales daily, and participating brands include heavy hitters like Badgley Mischka, Betsey Johnson, and Vena Cava. Like their competitor Gilt Groupe, most of Myhabit's sales will start at noon, so customers should have their mouses poised to click at 11:59 a.m. Get started with a membership by signing up here. Happy shopping!
