As of my knowledge cutoff in September 2021, the ability to pay online with EBT cash is limited and varies by state. However, it's important to note that the landscape of EBT acceptance online may have evolved since then. Some online retailers, such as Amazon and Walmart, have been participating in pilot programs to accept EBT for online purchases in select areas. It's recommended to check with your state's EBT program or the retailer's website to determine the availability of online payment options with EBT cash in your specific location.
