We actually have a small pharmacy in the pop ~1800 town near me. It seems to keep busy and I'm sure is great for older and other people who can't or don't want to drive a longer distance.
That said, as French mentioned, most rural people have to drive farther for other stuff anyway. If I need a prescription, I just get it when I make my Costco trip into the city.
Somewhat related, we had a little "field office" of one of the larger medical groups in Idaho in town here (fulltime PA, Doctor showed up a couple of days a week), but they closed last year and moved to the next little town over, about 30 minutes away. I went to them for my physicals when they were in town, but now that it's a 30 minute drive, I just drive an extra 15min to go to one of their larger medical centers in the closest city where more stuff is available.
