Amazon Whacking

I found a site called “Amazon Whacking” the other day.  The site describes a game in which you start with a book at Amazon, follow one of the links to “Customers who bought this book also bought”, then repeat step 2 until you cannot continue without repeating a book in your path.  The “world record” was listed at 61 steps.  This sounded miniscule, so a couple days ago I decided to try it myself.  Searching manually, without the aid of a script, I found one of length 319.  By that point I was getting a bit bored; I’m sure I could have extended it further.  I sent it in to the guy who runs the site, and he has just added it to the Amazon Whacking page as the new “world record”.
