If you receive an error message or notification that your transaction has been declined, first confirm that your credit card information and billing address have been entered correctly.
If you do not immediately receive an order confirmation message on-screen after submitting your order, do not click the "Complete order" button multiple times. This may result in duplicate orders being placed.
If you have questions about whether or not your order was successfully placed, log in using the account icon at the top of any page. If your order was successfully placed, it will appear in the list of recent orders.
