Let The Buyer Beware

This is kind of an interesting site:
http://www.infomercialscams.com/
It talks about all the different stuff sold on infomercials, and tells you exactly what the "catch" is. It explains all the scams and has thousands of horrific tales sent in from people who got scammed and screwed out of their hard-earned money. (If you fell prey to an infomercial scam, you can send them your story too!)
It's all there! Carlton Sheets, The Ionic Breeze, Aloette, Proactiv, Oxi-Clean, Nutrisystem...
One interesting twist is that the site also has a section for people who actually LIKED the product. So you can read complaints about things AND people's defenses of them.
Definitely do some research here if you ever consider buying anything from an infomercial.
There are a lot of unscrupulous hucksters out there.
