Handheld FRS/GMRS radios. Many preppers obsess about long-distance communications, but in a typical emergency, chatting with people 100 miles away is not a priority. In contrast, a hand-held two-way radio can be very useful for keeping in touch with your friends and family during any prolonged outage. Again, pick a device that accepts the kind of batteries you can stockpile cheaply. Expect a range of 2-3 miles in rural regions, and less than a mile in highly urbanized areas - no matter what the manufacturer claims. With all that in mind, Olympia R500 ($55) is a good choice.
Is this a complete list of everything you will need to be fully prepared food-wise? Heck no. Are the quantities adequate to feed a family for a month, three months or longer?

Truthfully, for long term storage you need more food and more variety (read about the top survival food brands here) as well as some packaging methods (Mylar bags or buckets plus oxygen absorbers) to insure that your will food stay viable and pest free for years to come.
