Can I order with my EBT card online at the Walmart in Brunswick Georgia and pick it up at the store

Yes use it as your payment option

Yes. I do it about once a week.

Yes

Yes, you can.

I'm not sure. I've never had an EBT card. I've never tried ordering online and then picking it up. But I think you can. I don't see why you could not.

Yes you can. Add your EBT card as a payment method for your online account.
