When buying a product online, look for well-known payment methods, such as major credit cards. Cards from the major issuers have zero-liability policies, which can protect cardholders if their information is used to make unauthorized purchases. PayPal is a common and trustworthy way to make purchases because it adds a layer of security: Shoppers input only their PayPal account information, not debit or credit card details. (Still, there are many scams that involve PayPal-lookalike websites or emails, so proceed with caution.) If a seller or online retailer asks for a wire transfer or personal check, that's likely a sign to back off. Once a check has been sent to an unscrupulous vendor, there might not be anything you can do to get the money back.
