Today at check-out: "Each time you place an order with us, we'll offer you the chance to participate in the Share the Love program by e-mailing your friends and giving them an additional 10% off the items you bought. (You select which items, of course.) The e-mail we send will explain the discounts and how to apply them. If anyone makes a purchase within a week, you'll get a credit to use the next time you shop!"

Is this new? Amazon.com turns its customers into instant affiliates paid in discounts on future purchases.
