We're sorry to hear you're having troubles with your credit card. We suggest the following:
1. Sometimes our system rejects initials or abbreviations when entering your address. For example, try leaving initials such as NW or SW out.
2. If the above solution does not work, we suggest trying another card. If you are sure it is not the card, please let us know. Our payment gateway provider is Authorize.net. They do have strict securities.
