Are the days of clipping coupons numbered? If supermarket chains have their way, they just might be. According to this article on MSNBC.com, several chains are testing paperless coupons. Instead of the traditional coupon-clipping method, shoppers load online discounts onto their store loyalty cards, then receive the credit at checkout. Some grocers, like Kroger Co., the nation's largest traditional grocery chain, are hoping to build loyalty among customers who are spending more and more time online. But this online process may not be welcomed by everyone. "If you're very computer savvy, this is probably a plus," said Peter Meyers, vice president of marketing firm ICOM Information & Communications LP. "But if you're more of a traditionalist, paper is very familiar and this is not."

Some stores are also offering in-store paperless coupons, which would cut the price electronically at checkout.
