Wallmart offering voice shopping service via Google Play

Hundreds of thousands of Walmart products are now available to purchase using your voice and a Google Home gadget or Google Assistant.
Walmart also integrated its Easy Reorder feature into Google Express allowing for simple repeat purchases.
Google intends to use the Walmart account link to offer personalized shopping results based on what you buy through Express, but also what you buy when visiting a Walmart store. So expect your Google Express recommendations to improve if you start using this new service next month.
As an added incentive to try Google Express, Google is offering free one-to-three day deliveries as long as your order is above a store's minimum. So that should apply to Costco, Target, and many others immediately, with Walmart orders getting the same option next month.
