They advertised these two whitening products to be used together for making teeth whiter in a sample form for a total of $21.60 and then two weeks later they bill you again for $79.95 saying that you agreed to a monthly charge if you didn't cancel within 14 days of receiving your sample products. You get no more product, but they claim that the sample was a 30 day supply and that $79.95 is the charge for a 30 day supply. Of course they will gladly cancel your future monthly charges but you are stuck with being charged $101.55 for $21.60 worth of merchandise. read full review »
