I’ve read that EBT cards can have 2 types of benefits. Food assistance and cash assistance. If someone is on temporary assistance for needy families for example, this money is put on their EBT cards and can be used for anything.
As a former front end casher working at Walmart you can’t use a food stamp card to buy a TV. And Walmart will have occasionally have great deals on TVs that other sellers won’t have.
Maybe it’s state by state. Mine has a cashier pay for the allowable items then pay for the unallowed items through other means.
