One thing that you should be aware of is that from 1/1/2015, the VAT ruling in the EU on e-books was changed.

Prior to this date, Amazon added 3% sales tax to your book's net price. Since that date, the ebook buyer's country, not the ebook seller's country imposes their particular VAT % rate.

This anomaly means that unless you manually change your book price on Amazon, you will see different Euro prices for your book in France, Holland, Germany, Italy & Spain. Ironically the VAT in France is only 5% whereas in the other four countries, it is somewhere between 19-22%.

The simplest thing to do is to have a universal Euro price across all European markets even if that means that you make a slightly bigger margin in some markets and a slightly smaller one in others.

For example with my recently published short story collection Impromptu Scribe which was released just before the new EU directive came in (Nov.2014) I have subsequently, since the new ruling, set a universal Euro price of 2.49.

If for no other reason, at least a universal Euro price is unlikely to confuse those European consumers who might choose to shop between different national Amazon stores e.g. Swiss buyers looking at Amazon.de, Amazon.fr and Amazon.it or Belgian buyers looking at Amazon.fr and Amazon.nl

I hope this is helpful in clearing the fog and eliminating the confusion brought about by overzealous European treasuries wanting a larger slice of Amazon's pie :-)
