Abstract:

Linda, an American living abroad in a country with limited merchandise, orders online for books, contact lenses, and smoked ham. Her Dutch husband buys from www.amazon.com and www.ebay.com because U.S.-based retail web sites offer a wide range of goods at a cheaper price than their adopted country, including lower import duties and lower shipping costs from U.S.-based cargo carriers.
