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.
