Many of our products are available at any given time. Due to the wide variety of items we carry along with heavy demand it is difficult to list what may be out of stock at any given time. We will take back-orders, however, on any out of stock products and will send partial shipments as items come back in stock. We do not charge any extra costs for multiple shipments and your credit card will not be charged for an item until that item ships. However, you may see card authorizations which are only used to check for available funds.
