Online sales scams target buyers and sellers on fake stores and marketplaces. A fake seller may take payment without sending goods; a fake buyer may send a false payment notice or claim to have overpaid.

• The price is far below comparable listings.
• A seller refuses reasonable questions or has a new, incomplete profile.
• A buyer asks you to upgrade an account or refund an overpayment.
• A website lacks business details, contact information, privacy terms, or secure payment options.

• Use trusted platforms and keep communications within the platform.
• Confirm money is in your account; do not rely on screenshots or emailed receipts.
• Check business details and research unfamiliar sellers.
• Do not refund alleged overpayments until the original payment has cleared.
