Why not just buy it? Alot of stores are carrying it, as well as through the TV and offer a 30 day money back return. If you don't like you havn't lost anything, and if you do your going to have to end up buying it anyways. Maybe if you just want to try it, you can offer to trade someone some samples if they'll send you a little sample of there's.
Actually, a friend sold me a set to try. My daughter wanted to try this, but when I looked into it, you had to commit to this monthly mailing. I just wanted to try it first before the committment. Although I know you can cancel at any time, those types of things are harder to stop than start! Thanks for the replies though.
