30 day return guarantee, with full refund including original shipping costs for up to 30 days after delivery if an item arrives misdescribed or damaged.

For international shipments, we might sometimes have to adjust our shipping cost after your order arrives, if we determine that the weight of the book will cause the cost to be significantly more than the standard shipping rate for your country.

We package all of our orders carefully either in a box that has been designed to ship books, or in a padded envelope. We want to make sure you receive your order in the best possible condition!

Our preferred shipping method is USPS Media Mail.
Recently, the USPS has added tracking to Media Mail , which has been a great addition to this service.

If you do choose to have your order shipped "Expedited", my shipping cost may seem higher than expected. Some of our books are large format hardcovers that can cost quite a bit when shipped expedited. So I would like to make sure that I can cover the cost upfront. However, if the actual cost of expedited shipping is less than the charge, I will refund the difference!
