I haven't read or looked at any poison bottle books, but I have noticed the one you are talking about on ebay. I saw it elsewhere for the same price but cheaper shipping. (Unless there are several different people selling those on ebay charging different rates for shipping.) I don't remember the URL but I guess I just typed in the book's name on Google to find it for a cheaper deal.
I would like to have a poison bottle book but every time I consider spending the money, I think about all the bottles I could buy instead.
