Query: Whats with the supplement promotion?

This book seems to have some pretty good information in it, so I'm not completley disappointed. BUT, I am so sick of having fitness experts try to cram supplements down my throat! I thought I was buying a no nonsense book from a world renowned strength coach, and what I ended up with was a sales catalogue for a nutritional supplement company. It even has pictures of several different products posted in the diet section of the book, with a 1-800 number at the bottom of each page so you can call and spend all your money on a bunch of candy bars and other junk that won't help you one iota with your training objectives. My advice: spend your money on something written by Stuart McRobert. The only thing he sells is good advice for the average weight lifter.
