We allow ordering for items that are currently out of stock, but that are expected to become available at a future date. Please note: we charge you immediately for pre- and back-ordered items, regardless of when the items will ship. We strive to provide the most accurate estimated arrival dates for pre- and back-ordered items where available. However, fulfillment of pre- and back-orders can be delayed due to unforeseen circumstances (delays from the shipping carrier, natural disasters, etc.). We will do our best to keep you informed of any delays to your order.
