The Amazon store is currently available only in six different countries – US, Canada,  France, Germany,  Japan and United Kingdom – but the good part is that you can buy books from Amazon.com even if you are not located in one of these countries.

The prices of books can vary across Amazon sites and then there are variations due to the currency exchange rates and the shipping charges which are different for every country.

Which Amazon Store is Selling your Book at the Cheapest Price?

If you are in UK, you’ll probably buy books from the Amazon.co.uk site while a person in US will prefer using the main Amazon.com site. That makes sense but what about international customers.

Assuming that you are in a country where Amazon doesn’t have an online shop (like India), should you use Amazon’s US store to buy books or the UK store since it’s physically closer so the shipping charges could be less. Well, you don’t have to do any maths yourself as there’s a new Amazon.com mashup called Cheap River that can help you compare and find the cheapest Amazon store for any particular book.
