My 80 year old wife decided she would believe the Shark Tank review of "True White System LLC" and try their "Free Trial Offer" -- Pay only S/H of $7.95.
Buried in the boiler plate at the bottom of the web page in very small print is "Terms & Conditions" that takes you to another page, needless to say she did not read this as she can barely see. They state that you have 14 days to cancel or you are automatically signed up for their program. My first clue that she had been "Had" was when I saw the charge for $149.95.
Called the number provided and think I landed maybe in the Philipines, they offered to cancel the account but would not refund the $149.95 charged for the product which she did receive, two small vials of peroxide and a generic tooth tray.
The scam is an old one, no one looks at the fine print on a remote page.
