If you pay by credit card,
1. Make sure your credit card has been activated, especially a new one.
2. Double check all the credit card information you have entered. You may have written a number wrong which prevent our system from recognizing your card correctly.
3. Check whether your credit card has expired. If this is the case, you should contact your bank for additional assistance.
4. Make sure you do not make a purchase that exceeds your credit card limit.
