Walmart has been working to address the needs of low-income shoppers for some time. More recently, it’s been introducing new ways to serve customers on public assistance. In fall 2017, the retailer began a small test allowing customers to pay for online grocery orders using their SNAP (Supplemental Nutrition Assistance Program) benefits — more casually known as food stamps. Today, Walmart says SNAP is now accepted for online grocery orders at all of the company’s 2,500-plus pickup locations.

For SNAP customers, the process of placing an online order is as simple as it is for those paying with debit or credit. They put in their zip code on the Walmart Grocery website to select their local store, then shop for groceries online by adding items to their cart. At checkout, they select a pickup time and choose “EBT card” as their payment option.
