Has anybody bought a copy of "Secret Guide to Computers & Tricky Living"?

There is a website called [url=http://www.angelfire.com/nh/secret/]SecretFun.com[/url] that is selling a book called Secret Guide to Computers & Tricky Living.  It's an interesting book on computers and life.

Oddly, the book is only for sale if you give out your credit card number via phone call or email.  This is odd because this book is supposedly written by a computer expert, but this person isn't using Paypal or something like it.  Is this a scam?  Has anybody ever purchased the book by giving out their credit card number?

Did some looking for this book and this expert is Russ Walters. You can call him and ask him computer based question and he will answer to you free of charge. Here's [url=http://www.secretguide.net/read/index.php?filename=introduction]this book[/url] to check out on WWW. This book is sooo old.
