When I put In the Valley stories up on Amazon for sale as a Kindle e-book, I priced it at $1.99 US. However when I searched for it on Amazon.com it came up with a price of $3.99; I contacted them to ask about this large price jump, and this morning received this reply
Your Kindle book is listed at a price of $1.99. Please note, all items available in the Kindle store are listed in U.S. dollars (USD), and the availability and pricing of titles from the Kindle Store varies by your home country or region.
If you're browsing in the Kindle store from a location outside of the US, you may see a price higher than what you listed on the DTP web site.
There are a number of reasons why prices for Kindle titles may vary from region to region, including taxes and other operating costs. We understand your concern about prices, and we share that concern -- we will continue our efforts to reduce costs and offer the best possible prices to customers in every region. We hope you will continue to use our platform for sales in the US and internationally. Also, note that the royalties will be based on the list price you provide on your DTP dashboard.
I hope this information is helpful. If you have any further question, please feel free to send an e-mail to email@example.com.
Thank you for using Amazon DTP.
Did I answer your question?
The question is answered, but I can't believe that with the Canadian Dollar almost equal to the US Dollar, a doubling in price can be legitimately explained as they have. Probably the answer is that they see an opportunity to make money on a very flimsy excuse - notice that 'royalties will be based on the list price you provide on your DTP dashboard.'
In other words, they will pay me 35% of $1.99, and keep the remaining $3.29 for themselves. Wow!
