Always be wary of unusually large orders, even when the customer is paying in advance by wire transfer (an extremely safe method of payment when performed bank-to-bank). Though the transaction could be perfectly legitimate, pay attention if the customer asks for your bank’s address or suddenly asks to pay by check instead of by transfer. In both cases, the customer may be about to pull a bad check scam. Both scenarios allow the customer to deposit money into your account by check. If the check is a clever fake and you accept it as payment, you lose both the money and the merchandise.
