How to build food storage without panic buying

By SGWNI. Checked on 2 November 2026.

To build food storage without panic buying, add one item you already use to each grocery trip, and keep going until you reach your target. That’s Ready.gov’s own advice: build your emergency supply kit over time, and add one regularly used item on each trip, especially if it’s on sale. You don’t need a big shopping day, a storage room or a special budget.

Why slow beats sudden

It costs less at any one time. One extra can a week hardly shows up on a grocery bill. Ready.gov also suggests watching for seasonal sales on emergency supplies, and looking for deals at garage sales and thrift stores.

You’ll buy what you eat. Ready.gov says to choose foods your family will eat, and food bought in a hurry often isn’t. Food you like gets rotated. Food you don’t like sits on a shelf until the date has passed.

You won’t be shopping when everyone else is. If you’re already set when a storm is forecast, you can stay home, and there’s more on the shelves for neighbors who couldn’t plan ahead.

Start with what you’ve got

Look through your pantry before you buy anything. You may have more food than you think, and less water. Our supplies calculator will show you which of the two is holding you back, so your first dollar goes where it counts.

Ready.gov suggests starting with what’s already in your home: a flashlight, spare batteries, copies of key documents. Older clothes that still fit can go in a kit instead of the donation pile.

What to buy first

Medicine. If anyone relies on a prescription, talk to your pharmacist or doctor about keeping extra. Sources differ on how much, so ask what’s possible for your prescription.
Water. At least 1 gallon per person per day. The CDC says store at least 3 days, and 2 weeks if possible. The CDC calls store-bought bottled water the safest and most reliable option. Tap water in clean food-grade containers costs less, and you replace it every 6 months.
Food that needs no cooking. Canned meats, fruits and vegetables, peanut butter, dried fruit, cereal and bars.
A manual can opener. You’ll need one unless every can has a pull tab.
Light and power. A flashlight, batteries, and a way to charge a phone.
Everything else on the list. Our emergency kit checklist covers it.

A slow build, in practice

This is an example for two adults. Adjust it to fit your household and your budget.

Week 1: Check what you have. Buy a manual can opener if you don’t own one. Fill and label your first water containers.
Week 2: Two cans of something you already eat, and a jar of peanut butter.
Week 3: One 24-pack of bottled water, or more containers to fill. A 24-pack of 16.9 oz bottles is a little over 3 gallons.
Week 4: A box of crackers, two more cans.
Week 5: Batteries for the flashlight you already own.
Week 6: Dried fruit, granola bars, and a recount.

By then you’ll be well on the way to a 3-day supply. Keep going at the same pace and you can reach 2 weeks. The slow-build planner makes a week-by-week list for your own household and timeline. It doesn’t use prices, because we don’t have reliable ones, and yours will vary by store.

You don’t need special food

The CDC says it’s not necessary to buy dehydrated or other types of emergency food. Staples from your regular store work, and they’re the things you’ll actually rotate through. If you do want freeze-dried food for a longer supply, that’s a separate decision, and you can make it after the basics are in place.

Be careful with anything that promises a complete year in a box. Ask whether your family would eat it, and work out how many calories a day it really provides.

If money is tight

Ready.gov says community food banks are a potential resource for food-insecure families stocking an emergency kit. It also suggests swapping clothes with friends or neighbors, and checking whether your local fire department has programs that provide smoke or carbon monoxide detectors.

Start small. One extra can a week still builds a supply.

If the news makes you want to act now

That’s a reasonable feeling, and there’s a calm way to use it. Pick one thing you can do today, like counting your water or finding your flashlight. Then add one item to your next grocery list.

When a storm is on the way

If a real storm is forecast and you’re not ready, buy what you need for your household for the next few days, and leave the rest. The CDC suggests filling clean water containers from the tap before a hurricane, which costs almost nothing. Ready.gov also says never to ration drinking water unless authorities tell you to, so aim to store enough to drink what you need.

Then, once it has passed, start your one item per trip. Next time you won’t need to think about it.
