Marketing scams

I have no problem with marketing products and charging money for it - be they spiritual or other. But what Bill Harris is doing is what I consider to be a huge scam. This is a recent letter from Bill Harris to all of us who are holosync users:"As you may know, each deeper level is more potent than the last. Why? Because we lower the carrier frequency we use to deliver the alpha, theta, and delta brain wave patterns you experience with Holosync." I believe this to be complete rubbish, and I haven't seen any research supporting these claims. If someone have seen this research, please let me know. It is one thing to charge great sums of money for something that we ourselves basically can produce for free (or that other people sell way cheaper), it is another thing to lie about what your product does. Bill makes this "carrier claim" over and over and it is time he back it up.
