this website promises that you get a free 14-day trial with payment of shipping. However, once you get the product, if you did not cancel the order, you will be charged outstanding amounts to your account. Not only that, their affiliates get your card number, and will charge to your account too. And don't try to refund, they say it was in their "Terms and Conditions." COMPLETE RIP OFF!!! DONT GIVE IN!!! CrestWhiteStrips, way cheaper, work better!
