Don't underestimate just how much of a value prop that something like this can bring to the table even if you do live in a city. I think of something like this as an ultimate convenience. Imagine you've had a long day at work, you've got family responsibilities or other plans afterwards, you're tired, you're hungry, etc. The last thing you probably want to do is spend even more time of your already busy schedule shopping for groceries.

Even with grocery stores nearby, you still have to go fight crowds of people, take all the time to find everything on your list, wait in line, wait to get checked out, then get your stuff and walk back to your place. A single trip can be exhausting, and even more so if you're introverted and/or hate dealing with crowds of people. Narrow aisles, the elderly, and annoying loud/crying kids can make for an infuriating trip if you're just trying to get your stuff and go asap.

Or... you could use something like this and have all of this taken care of for you.
