PayPal is a secure and trustworthy payment processing service which allows you to shop online. PayPal can be used at madtrendy.com to purchase items by Credit Card (Visa, MasterCard, Discover, and American Express), Debit Card, or E-Check (i.e. using your regular Bank Account). Madtrendy cannot see your card number as it is securely encrypted through PayPal's server. This limits the risk of unauthorized use and access.
