A sample of teeth whitening was advertized on the web. It was endorsed by CNN etc. ... The claim is you can try a sample of there product risk free for 6.99 shipping and handling. I received the product promptly. I did NOT receive any email conformation nor a contract in my sample. 2 weeks later I was billed on my credit card for $78.23. I called the company and inquired of this charge. They informed me that was the cost of the product for 30 days. I had been automatically enrolled in a month to month contract for a continued 3o day supply of the product. Because I did not mail back the unused product in 10 days (at my expense) I will be charged this full amount for the "sample".
