I got sent to Omax line through a survey as well, I thought something was a little fishy and checked the terms and conditions, here's what it says:
"...When you place your order today with www.omaxline.com, you will receive one of our Omax Watch products absolutely free (just pay shipping) for 14 days. Please note, the 14 day trial period includes shipping and transit time. ... If you do not cancel within the allotted 14 day grace period, we will assume you have decided to keep your purchase and therefore you will be billed $95.00 for it. You will continue to receive one of our exclusive items every 30 days for the low price of $49.99 after your initial 14 day trial period until we receive a cancellation notification. "
