Pay by credit card rather than debit card. Credit/charge card transactions are protected by the Fair Credit Billing Act. Cardholders are typically only liable for the first $50 in unauthorized charges. If online criminals obtain your debit card information, they have the potential to empty your bank account.
Never email credit card or other financial/sensitive information. Email is like sending a postcard and other people have the potential to read it.
