Hi Jacob, great comment. Many folks in Chennai, not just my mostly-disabled grandma, take advantage of the services in India. Every day the delivery boy from the local market drops a small quantity of vegetables off at her flat. (She can store vegetables with thick skins for a couple of days - such as carrots, squash). This is also true of the man who brings her a fresh coconut and breaks it in front of her to give her the coconut water, the flower woman who delivers flowers every day for her religious efforts, and the water guy who brings a big tank of water every few days. This delivery service is extremely affordable (sometimes free), mostly because it's so localized.
I live in the US as well; maybe we could think about delivery service options for daily cooking. Maybe in urban areas, companies like Blue Apron or Amazon Prime or Google Express could make an impact on food delivery.
