I have earlier ordered some CD's and DVD's from Play.com - a cheap online store with free international delivery. Now they started to sell books as well! With free international delivery! Great prices, for example all books from Dan Brown at £4.99. That's great news for me as a Norwegian because importing books is tax-free and the prices on books here in Norway are regulated by the government. So for example 'The Da Vinci Code' would cost me £7.50 + delivery ($2.50) from a Norwegian online book store.
Another great store with free international delivery is CD-Wow.com. Their website is not the best one and like Play.com, the selection is far from what you have at Amazon. But the service is CD-Wow is actually great, something you don't normally experience with these type of low-cost suppliers.
