We accept Visa, MC and American Express which is processed through a secured 3rd party site. When you place an order and submit your credit card details the total is authorized and hold only. After we check stock, fill the order and make any adjustments (ie. out of stock items, add shipping if an International order), we process the card only for the merchandise sent. If we are out of an item, it will be deducted from your order. We do not back order items.
