Hello Kayos.,
Your card was declined because it did not pass the Address Verification System (AVS) check. This indicates that there is a discrepancy between the billing address entered for the card on Paizo.com and the billing address your bank has on file for the card. Please let us know if you require any assistance updating the billing information.
Authorizations are not charges, but they will often put a hold on funds in your account and they occur each time our card processor is asked to contact your bank to check if the card is good. Authorizations typically reverse a few days after they appear, when your bank chooses to release the funds. Authorizing again will place a second temporary hold (that will hopefully be accepted and become the final charge), but the first will be released when your bank drops the hold. I can make this happen a bit faster by putting in an authorization reversal request, which I have already done.
Ensure that billing address is correct and let us know if you have any questions or concerns. Thank you!
