If you were to run into errors on the checkout page, you could find that there are pending authorizations that stem from declined transactions. Many times, we see this happen when the billing address for the card is entered incorrectly or is not what the card-issuing bank has on file.
Because these are only authorizations for failed payment attempts, we will not collect this money. These authorizations could hold on your account for up to 3-5 business days, but will then positively fall off.
Rest assured, when a payment is successfully collected for an order, you are promptly sent an order confirmation within minutes of the confirmed transaction.
