We attempt to keep stock on all products. However, sometimes current orders deplete stock on hand and items that appeared in stock for your order will not be available. Should this happen, you will be notified to discuss your options. Orders that contain back ordered items will not ship until your back ordered item is in stock, however, 'partial' shipments are available upon request. Additional shipping fees will apply. Replenish dates listed on Back Ordered items are not guaranteed and are estimates and can change. Please contact customer service to address any questions you have about back ordered items or partial shipments on your order.
