Walmart has expanded its online grocery service network through adding delivery companies Point Pickup, Skipcart, AxleHire and Roadie.

The four companies will support the retailer to deliver groceries in metro areas across four states.

The expansion marks the company’s grocery delivery service available in more than 800 stores. The retailer also plans to expand the service to more areas by adding another 800 stores this year.

Walmart US digital operations senior vice-president Tom Ward said: “Customers love our grocery delivery service. As they are busy managing jobs, soccer practice, dance lessons and social schedules we are on a mission to do more than keep a little extra money in their pockets.

“With the help of these new delivery partners, we’re making grocery shopping even easier by bringing the everyday low prices of Walmart right to the front door of customers.”
