As of today, the paperback edition of Photographer’s Guide to the Sony DSC-RX100 is listed for sale at Amazon.co.uk. The process by which the book becomes available there takes quite a while, and for now Amazon does not have the book in its warehouses or otherwise available to ship directly to customers. However, the listing is there, and I have listed copies for sale as a third-party seller through Amazon Marketplace, using my seller name of White Knight Press.
If you are located in the U.K., you will be charged only the local shipping cost of £ 2.80, even though I ship the books from here in the United States. I am charging £ 16.95 for the books, and I have just received a large shipment, so I have plenty of books to sell.
If you would like another option for purchasing the book, CameraBooks.com, located in Oregon, is an excellent online seller that has the RX100 book in stock and is known for quick and efficient international (as well as domestic) shipping.
