Protect Your Money Before You Pay+

Safe Bets (You can get a refund)

  • Credit cards
  • PayPal (specifically "Goods and Services")
  • Escrow services (where your money is held safely until the goods actually arrive)
  • Letter of Credit (best for large, bulk orders)

Red Flags (Your money is gone for good)

  • Wire transfers to personal bank accounts
  • Crypto
  • Western Union or MoneyGram
  • Gift cards

The ultimate warning sign: If a supplier refuses cards or escrow and only pushes for non-reversible payment methods, walk away immediately. This is the number one sign of a scam. Either insist on escrow or drop the deal.

Double-check the names: The name on the bank account must perfectly match the officially registered company name. If it doesn't, stop right there.

First-time orders: Always use an independent escrow service for your first order. This ensures the supplier only gets paid after you have the goods in hand.
