These sort of grocery store operated delivery businesses exist pretty much everywhere in the US from what I have seen. They usually aren't advertised, but you can ask about them. I believe they are primarily used by the elderly, handicapped, carless, etc.
When I was in university, a few hundred miles away from my car, I would use the delivery services for very large orders (like 50 liters of seltzer water, or similar). Typically there is a minimum order size, a small service fee, and an expectation that you'll tip the delivery person (who is usually just a grocery store employee who is using their personal car).
