PLEASE NOTE: During Oak Knoll's Annual Site-Wide Sale, processing time may be longer than usual. All orders are processed in the order in which they are received. Orders in the USA are normally shipped using the US Postal Service. Other services such as UPS and air mail through the US Postal Service are available upon request. Foreign shipments are sent via USPS using either their First Class International or Priority Mail International option, depending on the weight of your order.  US Customs requires full value and content be listed on customs form - please do not ask us to reduce value or mark as "Gift".  

In the US, please expect a charge of US $8.50 for first volume and $1.00 for each additional volume. If ordering outside the US, postage is calculated based on the weight and destination of your order. Please note: we may contact you to request additional payment for a higher shipping cost, should your order be heavier than expected. 

Books are returnable within two weeks, but please notify us before returning a book.

Thank you.
