Your Budget-Friendly 72-Hour Kit Breakdown
Here’s a cost-conscious list that covers the basics: food, water, shelter, first aid, tools, and comfort. Prices are approximate and based on what you can find at stores like Walmart, Dollar Tree, or Amazon.
1. Water & Purification – $10
3 gallons of water per person = $4 (buy jugs or refill used containers) Water purification tablets or bleach = $2–4 Collapsible water container (optional but useful) = $2–4
Pro Tip: Unscented bleach can purify water—8 drops per gallon.
2. Food – $20
Canned goods (chili, beans, tuna, soup) = $10 Granola bars, trail mix, crackers = $6 Instant oatmeal, dry pasta, or ramen = $4
Choose items that don’t need refrigeration and have a decent shelf life. Don’t forget a manual can opener!
3. First Aid – $10
You can build a solid kit at the dollar store:
Bandages, gauze, alcohol wipes Antibiotic ointment, gloves, tweezers Pain relievers (aspirin or ibuprofen)
