Would you like a sale receipt?

May I just set the record straight?
There is no reviewer copy if you are not a journalist or a book critic. If you are a friend and would like to support me (will be greatly appreciated), please purchase a copy from me.
Please note that printing a book is not free and as a self-publishing author, your friend Raymond (me) is actually paying from my very pocket. So, if I ask you subtly “Would you like a sale receipt?”, you know what I mean. Please don’t make me ugly and send you the bill later :>
