Over the last year, Walmart has taken several big steps to merge its online and in-store experiences with the rollout of services that let customers pay for items in store on mobile devices. In January, Walmart announced Scan & Go, a service that enabled shoppers to checkout on their smartphones. It aggressively expanded that offering only to end the rollout just as quickly. Next, in April, came Checkout With Me, an option that allowed shoppers in Walmart Lawn & Garden departments to pay on the go via mobile devices held by store associates. Now, there’s an app to buy online from a store associate while inside of a store.
