Easy-peasy! If you have paid with a credit card in the past, just head to the Shipping & Payment page in your account and the card you enter will become the one we have on file for your future orders. If you have linked your PayPal account, be sure to update it through Paypal!
Unfortunately at this time, our system does not have the capability to remove your Paypal account in favor of a credit card. We're sorry for any inconvenience this causes!
