Walmart is effectively competing with Amazon and utilising stores as their weapon in this battle. Also they are actively investing in or purchasing new startups which provide last mile delivery capabilities quickly. This is an interesting model to source innovation and stay competitive.
“We think the future is a combination of digital and physical retail,” said CEO Doug McMillon during the chain's October call with analysts and investors. “Customers are shopping in-store, online, with apps and mobile, a little with their voice and in time, with AR and VR and whatever comes after that. And they'll do so seamlessly.”
