Buy and Sell Safely on Online Marketplaces

Local marketplaces are great for deals, but come with risks. Safe habits matter.

Step by step

  1. Meet in a public place. A police station parking lot if available.
  2. Bring a friend. Especially for large items.
  3. Use cash for local deals. Avoid overpayment checks.
  4. Do not share codes. A verification code sent to you is a scam sign.
  5. Trust your gut. Walk away if uneasy.

What to expect

Expect friendly deals and the occasional scam attempt.

Mistakes to avoid

Do not share verification codes. Avoid paying before seeing items.

A good next step

Meet at a police station lobby if available.
