Do not fall for their "two for one" deal - the stuff is so expensive, it's still expensive even at half price, and then you will be stuck in their automatic billing system and will be unable to get out!
I just called to disconnect the automatic billing and instead of complying, the customer service rep kept arguing with me to convince me to stay on it. I kept interrupting him to say all I wanted was to stop my automatic billing and he would not help me, he just kept ignoring me and giving me the fast-talking sales hype.
I even told him that if he did not stop talking and disconnect my billing immediately, I would be really mad. He ignored that too!
I tried contacting the company by email instead - no reply. Buyer beware!
