"You know so and so took this product and their (insert malady here) totally went away. You have to try this."
Shows me a bottle of _______ product, that is bound to cure what ails ya. But you can only buy it through a distributor. I take a shot. It's not horrible. But, what is it?
I am curious, so I go online to find the product to see what is in it. You can't see the price until you have given all of your personal information away. I don't want a phone call, I don't want to see any "opportunity" – I just wanted to know what I ingested.
