Cancellation policy

Pre-orders
When you purchase a pre-order, you are buying an out-of-stock or soon-to-be-available product not yet in inventory. We may collect no payment or a partial deposit at checkout, store your payment method, then fulfill and charge the full or remaining payment at a future date. 
You can cancel a partially paid pre-order that hasn't been fulfilled yet. If the order has been fulfilled, you can't cancel it, but you can request a full or partial refund. See our returns policy for more details on returns and refunds.

In cases where books were purchased on behalf of the customer, orders cannot be canceled after the book has already been purchased from the supplier/publisher.
