I am constantly amazed at the number of sales that we have Internationally. The best countries are Canada, England, Australia, Japan, France and Germany. I think one onf the reasons is the reasonable shipping charges (USPS) for items that weigh less than 4 pounds. These can be shipped First Class Mail International for very resonable rates. In addition, The Endicia mail service allows you to buy insurance on these items to most countries. I think the combination of these two things are rerassuring to the international buyers.
Another service we use is the My Stores Map, a service that we include in the bottom of our eBay listing that show the country (state) where each one of our orders are shipped. This also gives the international buyers a safe feeling knowing that we understand how to ship to international countries. For example, we have shipped 147 orders to England and 74 to Australia.
