Through Saturday, designer resale shop Fashion Project offers a collection of 100 designer pieces for up to 85% off the original retail price, all under $100. Plus, new customers can use promo code WELCOME10 to take an extra 10% off your purchase. (If your order is under $70, use WELCOMESHIP to bag free shipping instead, which saves you a little more.) The pictured white size 8 Tory Burch Flats, which normally retail for $249, are priced at $60, ship free with code WELCOMESHIP, and a portion of the proceeds benefit Autism Speaks. (Update: these particular shoes have sold since we first posted, but there are still plenty of deals like it!) Other designers featured in this sale include Coach, Prada, Diane von Furstenberg, Lilly Pulitzer, Michael Kors and many more. A portion of proceeds benefit several charities. You must log in to access the sale, but sign up is quick and free. Please note that sizes and quantities are very limited.
