I do have a real difficulty regarding the meal kit services above as essential. They started off as a convenience for affluent time poor people. Having time shouldn't be a problem for anyone over the next few weeks and/or months.
If you think about it from the point of view of reducing everyone's interactions with other people, meal kits are another form of bulk food delivery. It's clear the supermarkets can't keep up with the demand for delivery, so having other companies able to deliver a week's worth of food is helpful. What we want to avoid is everyone heading to the supermarkets every few days to buy food. Of course some people will still have to - but if we can reduce that number by delivering meal kits, so be it.
