How many weeks of stock do you think is necessary?

How many weeks (or months .....) of food and other items do you think we need to put by in preparation for a deal Brexit in 2021?

Definitely Blackeyed, I'll like to stick something up Boris's nose but that is another story

Since the start of the year we have tried to buy for two weeks ahead, so we buy our normal things each week but use what we bought a fortnight earlier. Only exceptions are with some perishables.
