An affordable way to send large quantities of books overseas is to use the U.S. Postal Service's M-bags (large, canvas duffel bags) for "bound, printed matter." Please visit the United States Postal Service's website for more information about M-bags.
If you choose not to use the U.S. Postal Service's M-Bags, or if you are shipping items other than books, you may want to use the services of the following companies to ship large items overseas. Call or write to them for information:
Federal Express International
United Parcel Service (UPS)
International Sea and Air Shipping Corp.
