This was a sample tooth whitening for 1.00 and then suddenly 3.87 appeared.... and then i get a charge on my credit card for 94.00!!!!! FOR WHAT????? I called them and the man told me that i didn't return the item in time. I told him i returned to sender at the post office (which my postal woman distinctly recalls). He said there is no record. This is impossible as it had 2 addresses! Ivorypro and mine! It went back to sender. I am ripped beyond words. I will fight it with the credit card company at this point and see if there is anything they can do. DO NOT PURCHASE OR TRY ANY SAMPLE from this company. THey are a total rip off scam. It is absurd. Hope they get caught. Karma
