The Kroger Co. ( KR - news - people ), which operates the nation's largest traditional grocery chain, launched a website about 18 months ago that allows customers to download coupons to their store discount cards or onto home computers to print. The site added a mobile phone coupon app last year.

"We've seen slightly more complex couponing, which can take longer for us to help our customers exit the store," said Kroger spokesman Keith Dailey.

The so-called extreme couponers make up a small portion of customers and Kroger has not been forced to limit coupon use because of the trend, he said.

"But we're certainly keeping an eye on the industry," Dailey said. [unquote]
