Query: Avoid redundant ordering!!! This is a duplicated publication!

The material contained in this book seems to be useful, although I've yet to try much of it. What I want everyone to know is that this book and "Start Your Own Adult Web Site Business" are the same book, word for word. DO NOT ORDER THEM BOTH - YOU ARE BUYING THE SAME BOOK TWICE!!! These books have different ISBN's and purport to be written by different individuals, and have different publishers (maybe) but the contents are IDENTICAL - word for word, as best as I can tell.I will be trying some of ideas in these books in the next few months, and will report back with my findings. Until then, caveat emptor!
