Go to ebay and on the 'sitemap' page, (you will find a link to sitemap on the top of any ebay page). Once on the site map page look in the center column under the 'Selling Resources' heading..scroll down close to the bottom of the column and you will see the heading for 'Shipping Center'. Click on that and it will bring you to the shipping center page, then while on that page, click on shipping calculator, and it will explain what you need to do...Also if you have any problems,,there is also a link, called 'shipping calculator help' on that same page...
