16 CFR Part 425: "Rule Concerning the Use of Prenotification Negative Option Plans"
I've ordered a couple of free trials that were not free. One being Resveratrol. Although I canceled before the trial was over, I was still charged and told that I'd have to send back the bottle of resveratrol that was supposed to be free and of course, I had to pay shipping to send it back. No where did it say that the free trial would cost me anything other than the initial shipping and handling. They also sent another item that I had to pay to send back otherwise I would have been charged for that item as well. If something says free trial it should be free. This is a scam and it was very hard to get the charged reversed.
