When ordering online, you may backorder many (but not all) items that are out-of-stock. If an item is available for backorder, it is indicated by the word "Backorderable" beneath the FSS Price. Backorders are limited to one (1) customer order (shipment) and a maximum of two (2) backordered items per shipment. In other words, when you place your order we will ship whatever we have in stock immediately. We will send the second shipment when (and only when) ALL the backordered items are in stock.
