Hi OOFGOOF,
Your card is being declined by our credit card processing system due to an AVS failure. This means that the billing address you provided with your payment does not match the billing address your bank has on file. Before trying again, please double check that the address provided matches what your bank has on record. You should see the pending charges clear off of your account by tomorrow if they haven't already. Thanks for your patience, and let me know if you have any questions!
