I was thinking about how I would cope if I weren't able to rely as I do to a reliable on-line delivery service. Currently, we use a delivery service that is reliable and therefore menu planning is a part of the order process. We have virtually no waste and always have everything we need for the meal.
Same here. I love Ocado (I couldn't afford a Waitrose shop otherwise) and pre-planning the weekly order works an absolute treat.
I tend to do a midweek fresh food top-up (there are two decent mini-markets in King's Cross station, on my way home) and/or visit the Saturday market in my town.
Plus, the whole process takes half the time a physical supermarket shop takes, and is infinitely more civilised.
