Mobile Coupons

Who's Doing It: Kroger, Cellfire, Zavers
What's New: Companies are offering coupons on cell phones and online. Customers can save the coupons to their store's "loyalty cards" or simply show their phones to the cashier. For customers, the service makes saving money easier. It cuts costs for grocers, too, since they don't have to hassle with paper coupons. In addition, e-coupons provide real-time market data and boost customer use of loyalty cards.
