Yeah, where my Mom lives, the food options are:

• Walmart
• An erratically pricey local grocery, that rents its building (which has a leaky roof, requiring them to move product when it rains)
• Dollar General
• A farmer's market that's open once a week for a few hours before the afternoon heat, a few months a year, if no events have pre-empted it, having an inventory of which about 30% is bulk-bought supermarket produce with the labels (sometimes) removed
• A 90 minute drive; no trains, no buses (literally, no buses) to the next largest town

And she lives in a town people drive to, to get food, clothes, medicine, etc.

She gets as much as she can from the local grocer, for whatever that's worth; the inventory is frequently poor, & about on-par with Dollar General so far as brand-representation, goes. When tourists ask if the store has something, they get pointed to Walmart.
