Thanks to Bloglovin, I just found out about a great site called Mintbox. By signing up for a free account you will receive insider access to invitation-only sales, events, previews, and even cash back! Simply select your favorite stores from the list of retailers and you will receive notifications about sales and also special member perks (coupons) from the retailers you selected. By shopping through Mintbox you will receive 5% cash-back (15% through 6/24) on all members only purchases you make. Some of my favorite retailers on their list include ASOS, Barnes & Noble, Bluefly, Drugstore, Endless, Free People, Lord & Taylor, Macy's, NARS, Piperlime, Sephora, Shopbop, Sunglass Hut, and Target, but there are plenty others on the list as well!
That's it! There is no monthly fee. No skipping the month. Just sign up, select your stores, shop, and receive discounts. This is definitely my kind of site!
