You need to afford a computer of some kind, afford the premium for food delivery, and have a debit card in order to have fresh food show up in your food desert. Most people for whom living in a food desert is a problem are impoverished, and therefore don't have a car, don't have a phone/tablet/computer, and often don't have a debit card, and certainly won't pay the delivery premium. So this is not in any way going to help those living in fresh food deserts.
