BENTONVILLE, Ark. — Walmart announced an agreement with Postmates on April 10 to expand its online grocery delivery option to more than 40 percent of US households.

Postmates will start its service in Charlotte, North Carolina, with plans to move into other markets in the coming months.

“Customers are busy, they are managing jobs, soccer practice, dance lessons and social schedules; so, we are on a mission to do more than keep a little extra money in their pockets,” said Mark Ibbotson, executive vice president, central operations, Walmart US. “With the help of Postmates, we’re making grocery shopping even easier by bringing the everyday low prices of Walmart right to the front door of customers in Charlotte with more areas to be added soon.”

Walmart’s personal shoppers and Postmates’ delivery drivers will allow thousands of Charlotte customers to shop online for their groceries and have them delivered to their house. 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.

“Both Walmart and Postmates strive to make the lives of our customers easier,” said Dan Mosher, senior vice president, merchant lead, Postmates. “With our growing fleet of 160,000 couriers, we are confident that we’ll be providing Walmart customers with the ultimate convenience.”

The program includes same-day delivery. Consumers will be charged a $9.95 fee, and orders must be no less than $30.

The Walmart service, which was expanded in March, is now available in 1,200 stores, nearly 20 in Charlotte, with 1,000 more to be added this year.
