___________________
$611 Adjusted TOTAL The above will provide for what you would need to prep for in most emergency situations for 5 to 7 days for the protection of life and home that are separate from items you already own (add two large size tarps to the above if your don't have them). (I assume everybody has at least one decent size cooler, most probably have more than one, flashlights, plus their own personal clothing, coats, gloves, and shoes)
In addition as noted in post above Paper Goods are a great addition since it gets rid of having to wash dishes You may already have those around the house. (Also remember you can cook things on top of the kerosene heater if need be)
