25 Prepper Items To Look For at Flea Markets and Thrift Stores

Here is a fun article about finding survival gear at the flea market.

I also regularly use Offer Up, FB Marketplace, and Craiglist. You can find almost anything you would need.

Used items offer many benefits, here are a few:

• Older gear may come from an era where quality was king, unlike today. Many older items will have a quality and longevity not found in modern products.
• Buying used puts money directly back into your local community. Instead of a foreign manufacturer, or domestic corporation, your money goes directly into the pockets of someone in your community.
• Cheaper prices. Not all used gear is cheaper than modern equivalents, but with a keen eye you will SURELY find good deals on what you are looking for.
