I consider myself a convenience prepper! I shop in bulk and hold a fair amount "in stock" at home - my kids refer to the utility room as the shop. I did get extra in due to Brexit concerns, which I am now using up slowly, and will probably do that again towards the end of the year in preparation for January 2021 actual Brexit.
I generally have a fair amount in stock at home; stuff for laundry for several months (bulk buying), 25 ish tins of beans, a similar number of each of three soup flavours, 5-10kg of pasta, however many loo rolls are left from the last box of 50 ish we bought, a few kg spaghetti, 25 ish cans of tuna, 25 ish cans of tomatoes, 5-10 boxes of cereal, a few kg of oats/flour/sugar, 10 ish blocks of butter, 6 ish blocks of cheese, etc etc. I just use them and replace them every now and then so there's always some level of "preparedness".
My normal levels of preparedness are meaning I am not panic buying now. My natural disposition would be to panic buy, so I am glad not to be adding to the situation! I am continuing my normal shopping now, with a few extra meat items to stock up the freezer.
I live rurally and am comforted by the fact that as long as electricity keeps going we could be self-sufficient for a month or so (though I'd miss milk and fresh fruit/veg). To be honest if things went totally belly up and we lost electricity we'd be ok for a good while though there'd be a lot less meat!
