Please verify that the credit card billing address matches exactly with the information your credit card company has on file. The street number, street name, apartment number, city, and zip code must be an exact match. If the problem persists and your card is declining you may need to reach out to your card company. Multiple failed attempts may result in your card company placing a hold on the transaction for security purposes. If the problem persists, please contact us directly at support@alldayshirts.com for additional assistance.
