If an item that you ordered is not listed on the invoice that comes in your delivery, then this item has gone out of stock. We will only charge you for what we ship to you, so please allow 3-5 business days for your new total to reflect in your bank account. We will notify you via email regarding the out of stock item. We do not have a back order program, so if you see that this item has become available again, please place a new order online.
