Here’s the intro from this WalMart press release:
Earlier this year we announced a new way to make Online Grocery shopping even easier for customers – Walmart Voice Order – a service that gives customers the option to add items to their Walmart Online Grocery Cart by simply saying the words.
Today, we’re proud to announce that partnering with Apple, we’ve made Walmart Voice Order available on Siri. We are always looking for new ways to bring our customers the best experiences when buying Apple products from Walmart and when using their Apple devices every day.
We are introducing a new Siri Shortcut for Online Grocery. Customers simply ask Siri to start adding items directly to their Walmart Online Grocery cart after they’ve paired their accounts. It feels a little like magic on an iPhone, iPad, Apple Watch, Mac, HomePod or in the car with CarPlay.
Customers build out their basket by just saying “Add to Walmart” and then naming the product they want to add to their cart. After that, customers can place their order and Walmart personal shoppers get to work gathering the items for the customer, who can pick the order up on the way home or have it delivered right to their door.
