Is Nouveau Tech a scam?

I received a letter from this society also, on 12/26/06 stating that my life could change for the better financially, physically, romantically and emotionally, but i had to respond by 12/29/06. And, I did. They returned a 54 page booklet to me with examples of how 5 individuals lives changed after learning "the secret". In order for me to learn it, I had to pay them $139.00. Scam?............hmmmmmmmmm
