Selling internationally can be tricky. Countries have differing VAT on books and eBooks, and currencies also get in the way. Bookstores handle book sales using either an Agency or Wholesale price model.
To overcome this problem and protect your revenues, we created what a "agency/wholesale combo box". It allows you to control the revenues you get and/or the prices display for various price models/stores. When you publish a book, you will see:
The screenshot above shows that Amazon uses both an Agency and a Wholesale price model (that's what the "A" and "W" mean). The difference is whether the sale happens inside or outside the European Economic Area.
If you choose to give a base price according to the Agency model (as I did above), you see that the prices in the wholesale areas are increased (for instance to $4.99 in the US). This way, you keep your revenue at 60% of the base price you gave us. And so that is why your book price on those stores may be different to what you originally set.
The wholesale price model will give you 40% of the book's list price, not 60% (see more here), and so by increasing this list price, we make sure you get 60% of the price you originally chose.
However, you might want to maintain the same price for your book, whatever the area, even if it'll mean reducing your royalties for the books sold via the wholesale model. If that is the case, simply give us your base price following the wholesale model (as shown below):
As you can see, all the prices are now aligned. But why is the AUD price 3.99 then? Well that's just because the currency conversion is also taken into account, and 2.99 USD equals around 3.99 AUD ;)
