I'm seeing prices all over the place on various web sites. $29.99 up to $600. My bet is that the ones advertised for the low prices won't "ship within 2-3 days." I'm taking my Supers out of the safe to make room for the book.
The many sites that have $29.99 on the price were put up when the publisher had promised the paperback version, but then didn't/couldn't deliver. I don't know why the paperback never came out, but suspect a dispute between them and the author. I've searched for a second copy of this book many times on the net over the last couple years. I bought my pristine copy just before Xmas '05 for $25 on ebay. Even then, the price was more along the $75 and up range. So, I figure the bookstore that I bought it from didn't know the average market price.
