To help Free Shipping Day shoppers save on late-season holiday needs, FreeShipping.com will offer new and current members 20% cash back at every cash-back retailer on its site that day. Tom Caporaso, CEO of Clarus Commerce, owner/operator of FreeShipping.com, notes that members already get free shipping and 10% cash back throughout the year, so the double cash-back offer is intended to help them further enhance their holidays.
