Walmart has partnered with Point Pickup, Skipcart, AxleHire and Roadie to expand its grocery delivery program across four states. Walmart’s grocery delivery is currently available in more than 800 stores, and plans to be in 800 more this year.

To use Walmart’s delivery program, customers go online, place an order and then select a delivery window. From there, Walmart’s personal shoppers select your items and then pass it off to a Walmart delivery partner.
