To select your payment method, please go to the Personal information under Manage account and then select Change in the Payment section. Choose your preferred payment method and click Update.

You can also select your payment method during checkout, before you place your order. 

Please note:  

Updating a payment method in your account won't change the payment method on the order you have just placed. If you need to change your payment method once you have submitted your order, please contact our Customer Care team for assistance.
