ES Publishing uses 'Media Mail' to ship its packages... This is a very economical service offered by the United States Postal Service (USPS) and available for domestic mail to U.S. residents only. Since there is no parcel tracking with this service, you are required to purchase the 'Signature Confirmation' option to track your package status and also to confirm delivery, again only for domestic mail [USA residents]. Only one (1) charge is required per individual order / transaction.
