I have never quite understood why the panic buying is of basics. Looking back to the last war. Basics; bread, flour, potatoes were always available. It is the little luxuries that disappeared.
If I was panic buying it would be differents herbs, spices and pickles, stock cubes, jams and spreads, all the special flavour enhancing items that make basic food tasty and enjoyable. As it is tomorrow I will go to my local artisan bakery that makes properly proved and baked bread and the most delicious cakes and get a couple of extra loaves and a cak or two, so if we do have to self exclude for any reason we will be able to eat to the standard we are accustomed to. Nothing will go to waste, it will just go into the freezer until needed.
