"Ninety percent of Americans live within 10 miles of a Walmart store, and we serve more than 150 million customers a week, which gives us a unique opportunity to make every day a little easier for busy families," said Tom Ward, Walmart's U.S. vice president of digital operations.
Walmart is already growing its grocery pickup option where the order is brought to the customer's car, which is another trend in the industry also being used by its competitors. The option is in 1,200 stores with 1,000 more to be added this year.
