Walmart China has begun testing same-day grocery delivery in its Xiangmihu store.

The new Walmart To Go service is available within a WeChat mini-program, following Walmart’s partnership with online social networking provider Tencent earlier this year. It is currently undergoing trial with future rollout pending feedback from customers who opt in to the service.

Those ordering from the nearly 8000 SKUs available on the app can receive delivery in as little as one hour via a service provided by Dada.

Another of Walmart’s new mini-programs being tested at the branch displays a digital map that shows in-store shoppers inventory location and stock status.
