We accept US-issued credit cards as a form of payment. There is no surcharge for using your credit card to make purchases. Please be sure to provide your exact billing address and telephone number (i.e. the address and phone number that your credit card bank has on file for you). Incorrect information will cause a delay or cancellation of your order. We also accept other forms of payment, currently including Amazon Payments and PayPal for verified US addresses. We can not accept any form of payment from outside of the US, and can only ship direct to verified US addresses.
