Kroger's Cincinnati division began inviting local customers to order on-line and pick up at the store.

CINCINNATI — The Kroger Co. seeks to fuel continued growth by expanding its use of digital technology. Less than a year after acquiring, Inc., an on-line retailer of natural and organic products, the Cincinnati-based supermarket chain is leveraging the company’s e-commerce expertise to test and launch new platforms. In the Denver market, Kroger has introduced a new web site with its King Soopers division. Customers in the Denver area may shop for 36,000 natural and organic products on The products offered on the web site are free from 101 artificial additives and preservatives, according to the company.

“The web site, which utilizes Vitacost technology platform and fulfillment network, creates an endless aisle experience with ship-to-home service for thousands of additional health foods, vitamins, minerals, and supplements that are available in our Denver area stores today,” said Mike Ellis, president and chief operating officer of Kroger, during a June 18 earnings call with financial analysts. “We are excited to see the results of this new pilot program.”

Kroger said it will test the concept in the Denver market before expanding to other markets.

“Also this month, our Cincinnati division began inviting local customers to try our order on-line, pick up at the store solution we are learning from Harris Teeter, which we have been beta testing for a few months, and is now available in two of our Cincinnati area stores to all customers,” Mr. Ellis said.

Other efforts include the development of a mobile app and digital coupons.

“More than 2 billion digital coupons have been downloaded from our digital properties since we began offering digital coupons in 2009,” Mr. Ellis said. “It took four years to reach our first billion, and only 15 months to reach our second billion, and the third billion will take even less time.”
