To my mind an essential part of being prepared for lifes storms. The disaster doesn't have to be *htf but it could be the loss of your job, a natural disaster, ill health, huge unexpected bills or a family emergency. A store of shelf stable food and more in a chest freezer means the difference between eating 2 min. noodles for weeks or eating like a king (or a queen). Rules of thumb are: *Rotate your stockpile. *Stock what you eat. Eat what you stock. *Buy when items are on special and buy multiples. I find that items go on sale in cycles of approx. 6 to 8 weeks. so I don't buy that item until then. I buy and can meat when it's on sale. Canning makes the meat shelf stable for over 2 years. I write use by dates and price paid on the packet of the item in large print with a sharpie pen It makes it easier to keep track of used by dates and how much I spent on the item. Food is going up in price and the amount in the packets are going down. A stockpile is a hedge against inflation and it's hunger insurance. I also stockpile paper goods like paper towel and toilet paper. Petrol for the car and 9 kg bottles of gas for the camp stove. I live in a cyclone prone area so stockpiling and such comes as second nature.
