A special note to those placing pre-orders for upcoming publications...

In case you're wondering why your multiple-item pre-orders have been split, and are concerned about the shipping costs...

Due to a necessary programming function, pre-orders for multiple items or orders containing a combination of pre-orders and in-stock items are automatically split into separate orders for each line item. This occurs in case multiple pre-order items are received and shipping at different times. This allows each item to be filled promptly, without having to wait for other pre-ordered items to arrive.

We make every effort to fulfil your orders in as few shipments as possible, to minimize your shipping costs. Whenever we are able to ship multiple orders together, we will combine the orders and recalculate your shipping costs accordingly. Credit card orders are not charged until they are ready for shipment, so your shipping charges will be accurate at the time your charge is processed. If you paid by PayPal, we will refund any excess charges to your account once the revised and accurate shipping charge is determined.
