Copyright laws vary from country to country. Mass Explained contains several works of art that are in “public domain” by United States standards, but may still be under copyright in other countries. Therefore, books can only be shipped to U.S. addresses. International customers may want to consider using a mail forwarding company such as MyUS.com, Qwintry.com, Stackry.com, and Shipito.com. These services provide you with a U.S. shipping address to which “Mass Explained” can be sent. Once the forwarding service receives the book, they will then forward it to your international address. Please note that you may be responsible for additional shipping and customs fees, as well as VAT or GST taxes when using these services.
