If your order does not process, do not try to place the order again. Your order was not placed. Each order attempt may result in a credit/debit card authorization.
An authorization is not a withdrawal, but rather, a temporary hold of your funds. If an order is not placed successfully, the pending authorization(s) will usually drop in 3-5 business days for U.S. cards or 30 days for all other cards, dependent upon your bank. Note that there is no need for you to take any additional action for the pending authorization to drop automatically.
