There's a new player in the world of flash sales and this one comes from a familiar name: Amazon.com recently launched MyHabit.com. It offers many of the same benefits of other flash sale sites, including up to 60 percent off on designers labels of clothing, jewelry, handbags and shoes, including Nicole Miller, L.A.M.B., Kenneth Jay Lane and more. The difference is your returns are free and you'll receive credit, which can be used on MyHabit.com or Amazon.com. While not as ideal as receiving your money back, there's not much you can't find on Amazon, so using the credit shouldn't be a problem. Upcoming sales include Decades Denim and French Sole.
