I've got something very positive to say! I bought a book and of course should have been more careful and suspicious about the very cheap price. Only afterwards did I learn it was a pdf copy and not the real book. But now I own a pdf copy! I can read the book easily on my laptop or phone. And best, I can send the pdf copy by email to a few family members with whom I want to share the book. I'm very pleased! I will look for more books from Moonbokers.
Important: in your confirmation email, look carefully to see where to click to download the pdf.
It should be more clearly explained.
