I've just been reading katherine lowry logan's blog on writers tips and general info. She really does dig up some great stuff so I cannot take an ounce of credit for this one; she did all the work.
Have you spent time, and like me failing to get your Amazon listed book on every country to which they sell? Now you don't have to. With this one Link you can send readers automatically to their own country's Amazon page to sell your book. She explains it much better than I so have a look.
