BENTONVILLE, Ark. —  Walmart and DoorDash announced on April 24 they are partnering up to expand an online grocery delivery option beginning with the Atlanta metro area for America’s largest retailer. Walmart plans to reach more than 40 percent of US households with delivery options by the end of 2018.

Walmart’s personal shoppers and DoorDash drivers will allow thousands of Atlanta customers to shop online for their groceries and have them delivered to their houses.

“We’re connecting all the parts of our business to create a shopping experience like no one else can. With the expansion of our Online Grocery Delivery program, customers can have great items at everyday low prices delivered to their door with the click of a button,” said Greg Foran, president and CEO, Walmart US. “With the help of DoorDash, we’re delivering the best of Walmart to customers in Atlanta and beyond.”

After orders have been picked by a Walmart personal shopper, a DoorDash “Dasher,” retrieves the order from a Walmart store and delivers it right to the customer during their specified delivery window. Personal shoppers must complete a three-week training program to learn how to select the freshest produce and the best cuts of meat for online grocery customers.

“Our work with Walmart marks DoorDash’s official launch beyond restaurant delivery,” said DoorDash COO Christopher Payne. “We look forward to expanding across the country, enabling Walmart customers everywhere to spend more time doing the things they love.”

Walmart announced a similar program with Postmates earlier in April for the Charlotte area.

The program includes same-day delivery. Consumers will be charged a $9.95 fee, and orders must be no less than $30. Walmart also offers an online grocery delivery service that allows customers to order their groceries online and pick them up in stores. That service is now available in 1,200 stores, nearly 30 in Atlanta, with 1,000 more to be added this year.
