The thing most people run out of in a bad week isn't tea bags, it's knowing what's in the box. What has worked for households that keep a bit of a store: one list of what is actually in it, written once when it's packed, with the dates that matter, because the torch batteries and the tins are fine until the day you find out they weren't. The back of the cupboard door does it, a note on the phone does it, an app such as XNeuronal takes it said out loud ('emergency box: six tins, candles, batteries checked September') and tells you in March to look at the batteries again. JenniRen's point is the one to act on, though: if the surgery won't take the order more than a week before you run out and the chemist wants ten days, the reminder has to be on the box, not in the head. Count the tablets when it arrives, work out the run-out date, and set the reorder for ten days before it, every month. Then the storm can do what it likes, and the chocolate is a separate problem.
