Put down the scissors: Some grocery chains are trying paperless, or digital, coupons. Kroger Co., which owns Smith's grocery stores in Utah, is partnering with Procter & Gamble Co. to offer paperless discounts for P&G products through Kroger's Web site.

Still popular: Coupons for groceries date back to the late 19th century, and most U.S. households regularly use coupons, although redemption rates are low.

Save time, money: Some early users of digital coupons say they are convenient and offset the need to clip and organize coupons — and remember to bring them to the store. Companies also say digital coupons cut processing costs and paper use.
