>I'm wondering who in the hell chooses to drive, park, walk half a mile inside a flourescently-lit building, stand in line, pay, load a car, drive back to a house, and unbag groceries when all of that can be avoided by using a computer.

I've tried grocery deliveries. Invariably not everything you want gets delivered. Produce and other fresh items may not be as good as you expect. Maybe if I had Instacart with Whole Foods but then I'd spend more and it's not available where I live anyway. Lots of people aren't quite as adverse to getting up from their computer.
