If you pay by credit/debit card, your preferred payment method could be somehow unavailable at the checkout by our system in defense against possible credit card fraud.

Under such circumstance, here is the solution for you:

Step 1. Select PayPal (even if you don't have a PayPal account). Click on "Pay with PayPal".

Step 2. Click on "Pay With a Card".

Step 3. Fill in your credit card info and complete your order.
