I have a (discount) supermarket literally next door, but I still have groceries delivered once a week. The quality is better, the selection is better, I don't have to lug around cases of beer like I did at university. There is no venture capital involved, it's not cheap, they've been doing this for many years, and there is one delivery per week, ordered three days in advance.
