How is Walmart using e-commerce and technology to compete in retailing?

"After a slow start, the world’s largest retailer, Walmart, has begun moving into e-retailing in a big way. It is now in almost every major category of web-related consumer commerce. It is estimated that Walmart has approximately 200 million items across all of its outlets, compared to 300 million items available through Amazon. The company has taken some innovative steps to leverage the web to drive people to its stores. In 2016, CEO Doug McMillon purchased Jet.com for $3.3 billion and put Jet.com’s CEO Mark Lore in charge of running Walmart’s online business. A case in point is the company’s online tire service, which allows you to order automobile tires to be picked up and mounted at a Walmart tire center. Customers can order prescription refills for delivery by mail or for pickup at a Walmart pharmacy department. Walmart’s online photo service, in addition to providing a way to store pictures on the web, allows customers to send digital pictures to be printed in a Walmart store of their choice, with a one-hour turnaround."
