If your order consists of both available and out-of-stock items, you may receive multiple shipments so that you have the pleasure of reading the available books immediately. 

If you are missing items, please refer to your tracking numbers to determine whether they are still in-transit. If there isn’t a tracking number displayed next to your missing item, it likely remains out-of-stock and will be shipped as soon as it is available. Once it is on the way, the corresponding tracking number will then appear on your order page. 

If all items within your order are marked as sent, but some are missing, please contact us immediately so that we can investigate.
