Unauthorized charges to my credit card

I also got scammed by this company.  They sent me a second bottle and charged me for it and won't take it back nor refund my money.  I am sending a letter to my credit card company to fight the charge and the Texas Attorney General.  The caveat about future shipments is absolutely hidden in a grayed out, scroll-down box in 6 point type on their website.  This box with the caveat is also below where you click to "submit your order."  This is clearly deceptive.  We need to stop them from doing this to others.
