Given that I have to provide food and drink for 5 people two/three times per day means "grabbing something quick" is right out. Both on weight/carrying capacity ... and on price. This is not happening and I don't see how it is a serious suggestion. This is not about "allow[ing] the possibility of not living with a car", all your suggestions increase costs, some increase them a lot. And sure, with unlimited money, I understand that the center of a big city is more luxurious than the suburbs or countryside, this is not controversial. You get to drop the car, which is about 500 dollar per month. But you spend double that on the equivalent apartment (I don't mean equal sized to what you get in the suburbs, I mean the MINIMUM apartment for 5 people) So yes, costs will need to be comparable, as a basic condition. So using something between a convenience store and a "agent" supermarket is not a serious option, nor is fulfilling every meal by "grabbing something quick", not just from a weight/carrying perspective but from a financial perspective. Making the choice simply based on which is the closest is not a reasonable option either. The problem with a family of 5 is that every cost you have when you are single multiplies by a factor of 3-4, and I'm sure it'll be 5 by the time the kids really get past puberty. Furthermore, you haven't answered my original question: just simply how to carry it. I assure you a 2-3 day supply of soda for a family of 5 weighs minimum 6kg, and 12kg is better (even that is 3-4 days at best). Carrying this onto public transport, over the sidewalk and/or into an apartment block is supremely uncomfortable. Your suggestions change nothing except making it expensive as well. Let's take an example: 1 day breakfast + lunchbox + dinner for 2 adults and 3 kids. Take 2 bottles of soda (3kg), 2 cartons of milk (3kg), breakfast cereal (750g), 2 full size breads (750g), something to put on there (700g), vegetables (1.5kg), meat (500-750g), potatoes (2kg), and general supplies (2kg). This is three bags of groceries weighing 15kg. I assure you it definitely won't last 3 days. How do I comfortably carry this on public transport, and sidewalk, and up a flight of stairs, and you say to carry it on the way home, so in combination with what I carry to work (let's say 5kg) ? Going once a week, with, say 3 people, carrying something like 20-40kg of groceries, seems vastly more comfortable, attractive, cheaper, easier and faster to me.
