Hi there Farkwolf. Please verify the following steps to help you place an order online due to receiving an error while trying;
1. Please make sure the Billing and shipping address are the same
2. Please make sure you're using a valid credit card.
3. It is best if you use Internet Explorer as your Browser
4. Verify if your credit card has a block from bank to purchase on line.
Please verify these options if you continue to have issue please let us know. Victor21
Thank you. Try removing the card from file and then placing the order. Some times the system would try to match the card on file and if not match is found it would give an error. Victor21
