We do not offer returns except in the event of an error made upon our part (e.g., you received an incorrect or defective item). In such a case, you must return the incorrect and/or damaged item within 30 days of delivery for a full refund. It is also our policy to pay the return shipping costs as well.
Shipping costs depend upon the options you choose (e.g., number of books, hard copy or soft copy), and where the shipment is going. To estimate shipping costs, place an item in your cart and click the Checkout button. On the order confirmation page, you can play with different shipping options and preferences to see how the prices and delivery estimates change..
