I spent most of the $500 on these food storage items:  brown rice, white rice, pasta noodles, pinto beans, black beans, potato flakes, popcorn, buckwheat hot cereal, oats, cornmeal, flour, salt, and sugar.  The rest of the money I used on freeze-dried meat & veggies.  I also used some of the money to buy 5-gallon buckets to store the food in and 5-gallon water containers.

“If you’re using it for emergency survival, the fact is you’re going to buy it once, and hopefully you’re not going to use it,” Shields said. “But it’s there as a safety net for you and your family.” That’s what intrigued me about freeze-dried food: You can wait up to a quarter-century to use it, but in an ideal world, you wouldn’t have to eat it at all.
In theory, a person's natural right to self-defense is broadly recognized in much of the western world - but in practice, different societies look at it in very different ways. Today, in much of Europe, the very notion that one private citizen could lawfully harm another human being is met with suspicion and distaste; the control over life and death is more willingly delegated to the agents of the state.
For folks who want to focus on the most plausible risks, I suggest stockpiling dry survival rations to last around 2-3 weeks; seven 3,600 kcal packets per person should do the trick. That may sound like a lot, but keep in mind that it may take a while for stores to reopen after an earthquake or a flood - so it's not a bad plan to play it safe. And while eating ration bars for a week sounds bland, you may be in no mood for home cooking when you have to fix a collapsed roof and the utilities are cut off.

Of course, some "doomsday" preppers worry about even more exotic, post-apocalyptic scenarios mentioned in section 2.3, basically aiming for indefinite self-sufficiency. I don't think it's a particularly sound concern, but if the prospect of a civilizational collapse keeps you up at night, my best advice is to move to a rural community where you could farm, fish, or hunt. Some urban survivalists fantasize about trapping local squirrels, pigeons, or raccoons - but they would run out of food very fast. Small urban and suburban gardens are usually difficult to maintain and don't produce enough to feed a family, too.

Food storage cheap – Shop around.  Since I had a meager budget, I wanted to maximize every dollar that I spent.  This is where urgency can get you into trouble.  The more patient you can be the better the deals you can find.  First, investigate the stores in your area.  I was amazed the stores that I had shopped at for years had bulk items I never noticed before.  Second, check local store prices against online prices.  Third, get creative.  If you are working on getting cheese and powdered milk for your food storage see where the closest cheese factory or dairy is and how their prices compare.  I lived 35 mins away from a ConAgra Food Company (they make my favorite spaghetti sauce) and didn’t even know it.  I learned about it after moving to Idaho.  The more you research food storage items the better the price you will get for it.  
Your cyber-life matters - or at the very least, your bank account password and your credit card numbers do. To avoid falling prey to hackers, keep your software up-to-date, choose decent and unique passwords for all important websites, don't install sketchy freebies, and don't fall for legit-looking but unexpected messages and prompts. When in doubt, just leave the site you were on, do some web searches to understand what's going on, and maybe try again some time later.
For powering more serious electrical equipment, a generator is a popular choice for people living in the backwoods. That said, this option comes with an interesting trade-off: if you were ever to face a contingency that may last for a longer while, it may be more important to conserve fuel for driving, cooking, or heating, than to use it for keeping the lights on. A fully-fledged solar installation helps you avoid such dilemmas, but costs an arm and a leg. A possible compromise is a jury-rigged solar setup done at a smaller scale: if you hook up 100W panel ($160) to a deep-cycle lead-acid battery ($60) and a low-cost inverter ($30), you gain the ability to recharge laptops and phones, or even power several desk lamps, a decent-size fan, or a small refrigerator. The whole contraption costs around $250 and is easy to stow away if you're not very short on space.

Knives. Very lethal and dangerous at close quarters, but only provided that you have the element of surprise on your side. They require some degree of physical fitness and training to use well. Their value is diminished when facing multiple assailants or dealing with a gun-wielding individual: even if you stab them, you are probably still gonna get shot. In a handful of places, carrying a knife may be illegal or subject to somewhat confusing restrictions, so perform due diligence if you want to take this route.

I hope this makes sense to you. It sounds like you have already figured out that with a growing teen and two additional children in the household, this will be a good start but that more will be needed over time. By doubling these quantities my guess is that you will be better prepared, food wise, than 90% of the population. And even without doubling the quantities, you will be better prepared.
There’s been a general increase in anxiety across the board among people in the U.S. over the past year according to an online poll from Psychiatry.org. About 2/5ths of all adults are more anxious now than they used to be. Of course, you don’t really need to turn to polls or research to have a gut feeling for this. The sheer amount of chaos since the start of 2017 has been steadily increasing. Following a highly divisive presidential election events have spiraled to a point that it can be hard to keep up: claims of fraud, and collusion from both major political parties; an endless parade of hiring and firing of high level officials in the White House and on Capitol Hill; mass shootings; rising tensions with North Korea, Russia, China and Iran; accusations (and confirmation) of sexual harassment of many once-respected individuals; ever-growing racial tensions; the impending end of net neutrality; the big data scandals.
Basically I would think in terms of mixed contents for five gallon buckets. I always use Food Grade buckets only combined with good Mylar bags and oxygen absorbing packs. By mixed contents I mean bags of rice (white) beans various types along with pasta products etc. this way you do not expose five gallons of rice or beans all at once. This extends the overall life of your food supplies.
Sooner or later, you may find yourself unable to access your bank deposits for a couple of days or weeks. It could be a matter of IT trouble at your bank, of a lost wallet, or of being a victim of identity theft. Heck, take Greece or Cyprus: when the confidence in the nation's financial institutions is shattered, it's easy to get caught up in government-imposed bank closures and withdrawal controls. (Folks in the United States may also recall the forced closure of Washington Mutual in 2008, or several state-level "bank holidays" imposed to combat bank runs during the savings & loan crisis back in the 80s.)
"I had a dream not long ago that was sort of like God said, ‘I will show you these things,’ and that we’d lost both grids on the East and West Coasts, and I saw trains coming in, packed, standing-room only, from both coasts, and they were just releasing them into Mark Twain and everywhere. Those people were then forming little camps—15, 20 people per camp. And I saw a colored boy and a white boy, youngsters, and they were talking. And the white boy is talking, and he says if you steal wood from any of those people, only take one piece, because if you take more than that they’ll miss it. 
One school of thought popular in the prepper community is to convert some of your savings into commodity metals: copper, tin, silver, platinum, palladium, and the likes. All of them are easy to store, last indefinitely, and will certainly hold value far better than a fiat currency in free fall. On the flip side, you may still need to accept substantial loss: an economic collapse will disrupt industrial demand, causing the prices of many such commodities to slump.

If you can afford to spend more than $50 / week…. DON’T. You’re gonna make a lot of mistakes in the beginning so, the more your read, the less likely you are to buy overpriced food, guns and gear. Sure, you have to buy stuff but knowing which stuff to buy and having the right skills is much more important. Ideally, you should make a budget and then stick to it.

The whining and crying of the rich cowboy whose ears were damaged due to the lack of firearms training and precautions with proper hearing cover--absurd. This was the episode which ended it for me. No thanks. The person teaching self defense? Erm... in theory, great. But who honestly believes an out-of shape person is going to be able to defend against a well-trained, fit and armed attacker? Or two? Some of these people need to get their reality checked.
If you must take regular medications for a medical condition, you’ll likely want to pack an extra set in your survival kit. You’ll need to discuss the issue with your doctor if you require prescription medications, but don’t forget about over-the-counter medications you may need too. For example, if you often suffer from heartburn, you’ll likely want to add some antacids to your survival kit. Similarly, if you have allergies, you’ll want to pack extra antihistamines, and you may even want to include an EpiPen if an anaphylactic shock is possible.
I have a .30-.30 Win. lever action disguised as a Floor lamp with a shade. The shade is glued to a long dowel small enough to go down the barrell. The Butt Stock shoves and fits tight into a weighted block of wood like a christmas tree stand; and its loaded with one up the spout. Just pull out the shade and rod; stand on the base push gun away from yourself and pull up. Only 2 movements in the ready if you don’t count cocking the Hammer. It won’t fire unless you compress the Lever mechanism. Its already cocked anyway.

This award-winning series presents compelling untold stories and covers a wide array of provocative subjects. "Explorer" aired for 25 years -- the longest-running documentary series in cable TV history -- before being relaunched in 2015 after a five-year hiatus. Each monthly episode of the new "Explorer" takes a similar deep dive inside a story from the pages of a recent National Geographic magazine issue, taking viewers not only to the most remote corners of the globe but also to the furthest reaches of the mind and deepest crevices of history -- on urgent missions of discovery.

As you will undoubtedly notice, much of the content in this section has little to do with hardcore prepping; some of the chapters touch on seemingly banal topics, such as financial planning, community building, or the prevention of burglaries and car wrecks. You have heard most of this advice before - but if you are serious about dealing with adversities and shielding yourself and your family from harm, you need to internalize these rules, understand where they are coming from, and actually live by them every day.
The aforementioned short list aside, there are other substances that may treat conditions such as anaphylaxis (epinephrine), or diseases such as tuberculosis and leprosy (isoniazid), uncomplicated appendicitis (levofloxacin), cholera and anthrax (doxycycline), malaria (artemisinin), typhoid fever, skin infections, and MRSA (TMP/SMX), systemic fungal infections (fluconazole), intestinal parasites (albendazole), and so on. In many places, you could legitimately stockpile them without prescription, and some prepper guides will encourage you to do so; but if you are truly concerned about such emergencies, be very aware of the difficulty of properly diagnosing unfamiliar diseases, and the serious health problems that many of these products may cause.
15. 20 cans of Soup or Broth. The beauty of canned soups and canned broth is that they are a budget friendly.  Soups are an all-in-one meal solution. All you need is a can opener and a spoon and you have a meal ready to go.  For an extra satisfying meal, try using a can of soup as part of the cooking water for your rice.  Yummy! For a guide to making your own bone broth, see Donna’s guide here.
As for the remainder of your money, I suggest splitting it across two largely unrelated financial institutions with different risk profiles - say, a big national bank and a local credit union. As long as the deposits are insured by the government (as they normally are in the US and in Europe, up to a per-account limit), this approach greatly increases the availability of your money, and probably doesn't expose you to any substantially new dangers. Keeping all your savings outside the banking system is an option, too, but it's not necessarily a smart choice. With fiat currencies, this move does not truly insulate you from that many longer-term risks, but adds the very real possibility of losing all your funds to fire or theft.
When walking around town, keep scanning your surroundings and be mindful of people around you. If your spidey senses are tingling, just bail: make a sharp turn and sprint away. Don't worry that some random dude closing up on you at night might be perplexed or offended by your move. Don't freeze up if somebody hollers or authoritatively barks an order at you - complying is a very powerful instinct, and some assailants know to exploit it.
At seventy-seven, living on a tugboat in Sausalito, Brand is less impressed by signs of fragility than by examples of resilience. In the past decade, the world survived, without violence, the worst financial crisis since the Great Depression; Ebola, without cataclysm; and, in Japan, a tsunami and nuclear meltdown, after which the country has persevered. He sees risks in escapism. As Americans withdraw into smaller circles of experience, we jeopardize the “larger circle of empathy,” he said, the search for solutions to shared problems. “The easy question is, How do I protect me and mine? The more interesting question is, What if civilization actually manages continuity as well as it has managed it for the past few centuries? What do we do if it just keeps on chugging?”
Add any extras for your situation: For example, here’s our guide on prepping with food allergies and how to store EpiPens without power. Also consider special needs for pregnant women, small children, pets, people with disabilities or significant medical issues, etc. If you have poor eyesight, always have a pair of backup glasses and contacts in your emergency supplies.
Yishan Wong, an early Facebook employee, was the C.E.O. of Reddit from 2012 to 2014. He, too, had eye surgery for survival purposes, eliminating his dependence, as he put it, “on a nonsustainable external aid for perfect vision.” In an e-mail, Wong told me, “Most people just assume improbable events don’t happen, but technical people tend to view risk very mathematically.” He continued, “The tech preppers do not necessarily think a collapse is likely. They consider it a remote event, but one with a very severe downside, so, given how much money they have, spending a fraction of their net worth to hedge against this . . . is a logical thing to do.”
A survival kit should be considered mandatory equipment for any outdoor enthusiast. You never know when something will go wrong, placing your very life will be in danger. But, if you have a well-conceived survival kit with you, your odds of survival will improve greatly. However, it is important to understand those different people will require different types of equipment in their survival kit, and you must customize your kit to suit your specific needs and the circumstances you’ll likely face. This means you’ll probably want to avoid purchasing a pre-assembled kit, and instead put together your own. Below, we’ll explain some of the most important items to pack in a survival kit, as well as the things you’ll want to consider when assembling your items.
