The "cost" of this book is $6.95, and you get it instantly as a PDF download.
Well, I used to mail out physical copies. The printing, postage and padded envelope cost exactly $6.95.
About 6% of books we shipped out were getting lost in the mail. And some of them were taking nearly three weeks to arrive!
I figured you'd prefer get the book immediately, rather than having to wait a couple of weeks.
As soon as you place your order today, you'll be sent a email receipt 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!
Oh, and in case you're wondering ...
