I have heard of several different methods for purchasing food to make your 3 month supply. A lot of people purchase all of the food at once. Then, some people keep a piece of paper next to their food storage to write down any time they take a can so that they can purchase a new can to replace the one they used. Other people don't purchase any more of the item until what they have is gone.
Here is my method:
- When an item that I keep in my 3 month supply is on sale, I inventory how much I currently have of that item. Then I consult my Excel document to see how much more I need to complete my 3-month supply.
- I purchase this amount of the item, plus enough to last until the next time I expect this item to go on sale (usually 6 months). For example, my family eats approximately 6 cans of refried beans in 3 months. When refried beans go on sale, I look in my cupboard, find that I only have 2 cans, and then buy 16 cans, because I don’t expect them to be this price for another 6 months (12 cans to last 6 months, plus 4 cans to make a 3 month supply).
