Keep a stock of food in the home that will last you 1-6 months if you can. Do your best. Don’t store anything you wont use up in six months of normal life, it might take up too much room or expire before you use it. Once you have six months stocked up rotate supplies and replenish as needed.

Many things you may want for emergencies can be purchased at the dollar-more or less-store. Start there.*
