You need to start stockpiling food
You can do a lot if you start early. Unfortunately, “early” might have been yesterday. Now we're way past early, and you need a reasonable plan to get food supplies that will store well and don't cost too much.You've probably already realized that buying up extra cans of soup at the grocery store is a really stupid way to spend your preparedness money. You need a better plan. Every $10 you spend at the store might feed a person for a few days. You need more leverage, where you can spend $10 and feed a person for a few weeks.
Buy extra, use FIFO
Go ahead and buy more food than normal when you are out shopping, and set it aside. Use the “first in, first out” rule to eat your older supplies first. Keep rotating your supplies so you never abandon food way in the back.
Buy ingredients, not prepared foods
Ingredients such as salt, honey, oatmeal and wheat will last a lot longer than prepared foods like TV dinners, cereals, and food mixes. Naturally, as you purchase food ingredients, you will want to practice actually using them!
