Why did credit card payment fail? If you pay by credit card, your payment could be somehow denied at the checkout by our system in defense against possible credit card fraud. It's a good idea to call your credit card company or bank ahead of time to let them know about the purchase so that it doesn't get declined. Under such circumstance, here are 3 solutions for you: 1. Please switch to your other credit/debit card. 2. If you have a Paypal account, please try to pay by PayPal. 3. If you do not have a Paypal account, please select PayPal still at the checkout page & click the complete order button. Then you'll be directed to a page with access to both PayPal and Debit/Credit card payment (for the latter option, you don't have to register for PayPal). Then you can complete your order with your credit card.
