16 CFR Part 425: "Rule Concerning the Use of Prenotification Negative Option Plans"
The problem with UltraResV is that there really is no free trial. You do not receive 10 days of resveretrol for free. You only get a 10 day period of time which does not change the amount you are billed for a one month's supply of resveretrol. I cancelled after I saw my first billed charge. But unfortunately, my cancellation was done only 2 days after they had billed my card a second time. I never received the product from the second billing and it has been over a month. It is in dispute mode with my credit card company.
