Online grocery delivery is fairly widespread in the US at least in the general vicinity of urban areas. I've had Peapod available for over ten years in the Northeast even though I'm far enough out of Boston that I don't get most of the delivery service things.
However, the only time I've used it was when I had a broken foot and, while I could drive to the store or pick up one or two things, doing a grocery shopping was difficult.
At least at the time, they'd invariably be out of something I needed for a recipe and/or they'd make substitutions that weren't really what I would have wanted. Quality was "OK." Normally, it's not a big deal for me to go to the store and I just didn't love the service in general.
