Your list may be completely different from mine, but I believe the items contained in this list of supplies will be common to most people and more importantly will be required if you are going to be as prepared as possible if the manure hits the hydro-electric powered oscillating air current distribution device.  This list is not all-encompassing either. I am probably not going to have blacksmith supplies or leather working tools although I can see the use in each of those. This list is going to be for the average person to get by if we have a SHTF event, not start a new life in the wild west. Please let me know what additional items you would recommend and I’ll keep this list updated so you can print it out whenever you need to purchase items or want to build your supplies out.
The first item to go into the stash is the first item to be used up, and then when you head out shopping or running errands you replace the used quantity in the stash. So after eating a can of chili out of your emergency stash, for instance, you would replace the can with another one bought at the grocery. The next oldest can of chili would be the one you draw next time you need chili, and so on. This is known as “rotating” your supplies.
My two cents worth here. Go with 5 gallon buckets. Many purchased from the local donut shop at $1.25. My variation on Mylar bags and oxygen absorbers — a chunk of dry ice, about 3×4 inches. With this on the bottom of the bucket and little piece of paper towel over it, pour in rice or beans or wheat or corn or a mixture of things. Put the lid on, but do not snap it tight. Wait a few minutes until the bottom of the bucket is not real cold and snap the lid on. Dry ice, which is CO2, forces out the air in the bucket. I recently opened rice and a mixed container which had been sealed five years ago. Everything was fine. Obviously we did eight or 10 of these buckets at once. Got dry ice from the local grocery store. Be sure to wear gloves when handling it.
2. At least two ways to cook food in a power down situation.  I’ve used the Sun Oven for years (visit the official website here) and own the Stove-Tec Rocket Stove.  The Eco-Zoom stove is another version of a highly effective, fuel-efficient stove that weighs less than the Stove-Tec.  If the prices of energy skyrocket, and it looks as though that may happen in the near future, it will be a blessing to have alternative ways to cook food without cranking up the gas or electric range.
I opened my MRE and noticed that everything was still pretty much the same. You have food in foil packets although my packets weren’t in separate boxes. They did include the nutritional insert though and I never understood why they had the extra boxes anyway. Another thing we didn’t have when I was in was the handy ration heater. The ration heater is activated by placing a little water in a bag. The water mixes with an element and causes a chemical reaction that generates heat. You wrap your entrée in the bag,  and in 10 minutes you are supposed to have a hot meal. It didn’t work that way for me.
The other thing I want to point out is that there is a bit of redundancy to the solution and resolution of some the listed prepper mistakes.  It stands to reason that a mistake doing one thing will overlap with something else, and so, for the purpose of this article, I felt it was important to maintain those small redundancies.  Now that I think about that, isn’t that the prepper way?

Communication: Our preferred portable radio is the BeoFeng BF-F8HP 8-watt two-way radio. You don’t need a Ham license to listen to local emergency services and broadcast when SHTF — see our beginners guide to amateur radio. We like this signal mirror instead of the cheap acrylic ones that scratch and fade quickly. Also, try these tiny whistles and signal flare kit.

Perhaps for that reason, many of the practices that bloggers like Luther and Nygaard describe as prepping seem to blend into the world of homesteading, a brand of self-reliance more closely associated with living off the land. According to Gaye Levy, the Arizona-based writer behind the blog Strategic Living and the founder of Backdoor Survival, one of the longest-running woman-run sites in the space, the two aren’t exactly the same thing. “I think prepping is pretty clear: You’re preparing for a disruptive event that’s gonna turn your day-to-day world upside down. Homesteaders typically will have a plot of land. They attempt to grow their own food, they raise farm animals, and that is their job.”

Per #17: Consider 25 pounds of sugar, even if like me, you don’t use it; it can become like money because so many have a sweet tooth for it. Next: at least the same amount of salt. (I buy sea salt for the iodine within and it’s a mineral all animals need in their diets so it too, can be used like $$. Third: black peppercorns, in past history this was used as money everywhere along the spice routes. Why? Because they have a very very long shelf life without losing potency. Then buy a pepper grinder, coffee/spice grinder and/or a mortar and pestle.
Personal hygiene is even more important in emergency situations than during everyday life. We have so many conveniences at our disposal in our society. Yet many people don’t realize the challenges when those conveniences are no longer available. Personal hygiene is really about keeping clean and avoiding unsanitary conditions that can lead to illness.

In both his book Rawles on Retreats and Relocation and in his survivalist novel, Patriots: A Novel of Survival in the Coming Collapse, Rawles describes in great detail retreat groups "upgrading" brick or other masonry houses with steel reinforced window shutters and doors, excavating anti-vehicular ditches, installing warded gate locks, constructing concertina wire obstacles and fougasses, and setting up listening post/observation posts (LP/OPs.) Rawles is a proponent of including a mantrap foyer at survival retreats, an architectural element that he calls a "crushroom".[8]

If you managed to get lard and salt, you need to get some cornmeal as well because it is better to keep on hand than flour. Corneal requires fewer ingredients to make bread, and it has a longer shelf life. A few 5lb bags of cornmeal should last until the emergency situation ends. You can make a skillet cake using just lard, salt, and cornmeal and I had the pleasure of eating such food on various occasions during my camping trips.
Just be aware, if you have stored mixes like bisquick or cake mixes which have baking powder in them. Baking powder has a shelf life, after that shelf life, the bp isn’t stable so your product may not rise and/or may taste funny. Depending on what form of dry milk (powder as opposed to instant milk) is used, that can also make your premixes go bad.
“Everybody thinks about prepping as this big doomsday thing, like when the zombie apocalypse happens,” Luther says. “But really it’s a lot more likely that someone’s going to lose their job or that you’re going to have a major expense you weren’t expecting, like your car breaks down or a medical expense. So if you think of prepping as something to get you through those situations, it’s really almost like an insurance policy.”
Owning a cabin in a resort town gives the well to do an upper hand. When things get uncomfortable (too hot days in Florida for example) they head out for cooler places like Oregon or Washington). Sometimes younger grown children live year round at these second homes while attending out of State University or they may just have young family’s and parents who gave them huge down payments or the like. Such arrangements benefit all. If you think and act as the wealthy do, you don’t have to think like a bug. I have seen poor people spend thousands of dollars on weddings, even birthday’s, they could ill afford; when they might have provided their children and themselves a place to go for vacation, or, for other reasons.
After 15 minutes, I was startled to discover that the cereal had puffed up into a Kashi-like multitude of grains, flecked with tiny pieces of apple, complete with green peel, that looked just-chopped. It didn’t taste as good as it appeared: Eyeballing a fourth of the bag had resulted in a poor distribution of seasoning, yielding a flavor I can only describe as water laced with traces of cinnamon and sugar, though subsequent attempts tasted better.
