Shipping Fees


Within the US, via the US Postal Service's 4th Class Media Mail (7-10 days delivery time): $4.00 for the first book, $1.00 for each additional book.

Via Priority Mail for faster shipping (4-7 days delivery time) for most average-sized books: $7.00 for first book, $4.00 each additional. NOTE: Priority Mail costs depend on package weight and distance shipped, so unusually large or heavy books may require an additional dollar or two.

Internationally: Via Global Priority Airmail, US$ 25.00 per book to most destinations. If a book is too large or heavy to fit in the standardized Global Priority Airmail envelope, we will email you a quote for adjusted shipping.

Please note that these shipping fees are adequate for the majority of packages, but may occasionally need adjustment downward or upward, depending on your location and the type of book you've ordered. We will email you if adjustments are needed, so please keep an eye out for any follow-up emails.




Returns are accepted within two weeks for any reason, with prior notification (please notify us in advance so that we'll know to expect the book back).




We pack our books in bubble-wrap, and ship in a sturdy cardboard box, except in the case of standardized Priority Mail or Global Priority envelopes for international shipments. Credit card receipts, with numbers clipped for security, are included in shipment; written invoices are included only at customer's request.

We make every effort to ship books within 2-3 business days of receiving your order (often sooner).
