The AVS error is generated by your credit card provider to protect you from credit card fraud & does not originate with our card processor/sales portal.   When purchasing online be sure to only put in the numbers of the card (no spaces or dashes). Be sure that the name entered exactly matches the name on the credit card including punctuation (if your middle initial is on your card, include it as part of the cardholder's name). Use the drop-down for the expiration month and year. Be sure you have your most current security code for the card (3 digits from the back of the card – 4 digits on the front of the card for American Express). Make sure the billing address & zip code are entered exactly as noted on your monthly statement. Many credit card providers also require the address entry to be properly capitalized. Be sure to check off that you have accepted the Terms & Conditions. When accepting the Terms and Conditions, you must scroll to the bottom of the T&Cs box and click "Agree" to proceed. If you are still encountering problems, first try clearing the browser history on your device then give us a call (Mon – Fri 8 AM – 4 PM).
