A 3 month supply would include everything you would need to survive independent of any amenities for at least 90 days. It doesn't cost a lot of money, nor does it take up much space to store. You would need food for three months and I have created a chart detailing the storable foods that would be included in a $200 3 month food supply. 3 months of water at 1 gallon per day is 90 gallons. Water containers don't cost a lot of money. A propane backup would be best for cooking the food. Along with batteries, flashlights, hygiene products, cleaning products, and anything else you use on a daily basis.
Before you start storing anything you must have a plan. A plan for yourself, or your family. Laying low at your home is possible but you have to remember that others who didn't store could be pretty hungry so you must stay low so you don't have people lined up at your front door to get food. Cook indoors, never "flaunt" what you have. This is where your operational security comes into play. So bottom line, get a plan together. If you need a starting point, start with 3 months for each person in your family and go from there. Use my chart as a guide. The information is there so there's no reason for you not to be prepared.
