Credit card processing for Ultradrives is done through a secure payment gateway operated by Paypal, a Wells Fargo affiliate. Upon checkout, you will be given the option of using your existing Paypal account or a credit card as means of payment. To pay by credit card select the box that says Click here if you currently do not have a Paypal account. Through this gateway, your payment information, shipping address, and billing information will be verified. If this process fails, you will not be billed. You may access your account through our site and complete checkout process without double billing occurring. Below are sample screenshots of this process. If you have any questions please feel free to call the sales department. Thank you.
