Query: Don't waste your money!

Wow, what a piece of garbage! I read the reviews on this page and thought I made a good choice. Not! I sent it back to Amazon.com, after reviewing it for 20 minutes. This book doesn't tell you why or how to, it gives you lousy information that can easily be found through public sources. I've found "the offshore money book" by Arnold Cornez to be much more valuable...
