The "cost" of this book is $6.30, and you get it instantly
as a PDF download.
Well, I used to mail out physical copies. The printing ($3.50 ea) and postage ($2.80 ea) cost exactly $6.30.
Due to the COVID 19 pandemic, it's been taking three to five weeks for books arrive! Even if you order it directly from Amazon.com.
I figured you'd prefer to get the book immediately, rather than having to wait a month!
As soon as you place your order today, you'll be sent a email with the download link where you can get it.
From there you can download the book and read it.
You can access your book anywhere, instantly, without having to wait for the post office to get it to you!
