In all seriousness, buy a 2 pound bag of rice, a box of powdered mashed potatoes, a bag of dried beans, some powdered milk every time you go to the store for you and the family, it’s not great eating but with the right seasonings you can ride out most serious emergencies in relative comfort, all for about $12 bucks extra each trip to the store. Flour, cornmeal, sugar, salt,coffee, filters, percolator. Propane, firewood, kerosene , diesel.
Urban types seem to get very concerned about water and buy up the bottled stuff when storms or viruses are headed in. Stupid, wasteful, and expensive. Better to buy filtration and storage equipment. Half filled gallon ziplocks freeze nicely, prevent food loss if the power goes out and keep water on hand. Rubbermaid tubs will hold a ton of tap water for short term problems if you have time to prep at all ( you usually do).
Keep seeds on hand, you can buy them on amazon but they’re waayyyy cheaper And of better quality at farm supply stores. obviously lead, powder, brass, primers, Spare parts, spare firearms. Keep a couple pairs of brand new shoes in storage and a mess of extra socks, if the feces hits the primary air mover, we might end up waking a bit more.
