I sold my first book to an Australian woman. The price of the book was 25.50. The postage and customs fee was 24.34. Well, at least the book is getting some exposure. Next time I will know. And since selling a book for nearly $50 is absurd, I will next time offer a digital file via email.
I’ll have to find out the postage of different countries so that I will know how much the postage will be in advance. I just tell myself, hey, the first one is free!
