Just because you are located in the US, does not mean that all your potential customers are also in the US. As I browse through many company websites (both large and small home-based ones) I am astounded at the number of businesses that do not include any information or reference to international shipping.

While most have a shipping info page, it usually contains shipping rates for the US, but nothing on international destinations ~ including whether the business will even ship internationally. As a Canadian who makes many purchases from work-at-home moms, I am constantly emailing people to find otu whether or not they ship to Canada.

You should always include shipping information for international destinations. This does not mean you have to go out and research every possible country for shipping rates to post them on your site. Even a simple "Please email me with your mailing address for shipping rates to international destinations." With the USPS (United States Postal Service) online rate calculator, you can quickly determine shipping for those of us who live outside of the US.

If you find you are constantly shipping to a particular country such as Canada, you can easily update your shipping information to include the shipping rate to that country, saving you from answering the same question via email.
