When is it ok the buy a book the Costs $300
 

If the book is out of print and it can make you have the greatest emails and faxes you can imagine. But the good news if you can accept a PDF file you can have it for much less. "Tested Telegrams and How to Write Them by Elmer Wheeler is $300 when you can find it. But soon I will tell how to use it for emails and faxes and get it for only $29.95. And you can download and get it made into a book, I will tell you how. I did it. Believe or not the book was published before I was born in 1941 and you can use it for faxes and emails in today's world.

I have seen some awful emails and faxes by people in large corporations with a MBA. You have too, I am sure.
