Yes. We use secure server certificates from Trustwave, a leading certificate authority. This means your information is safe as it is processed through our cart. In addition, our payment processors (Authorize.net, PayPal and Google Checkout) all use their own secure servers for their part of the transaction. Your credit card is never saved on our server or in our database. We have also passed our PCI compliance tests from Trustwave. Credit card details taken during a phone or fax order are immediately shredded and destroyed after the order has been processed. You can feel secure using Promolife.
