You buy the kit and then you commit to having it shipped to you every few months, I chose 6 months and every time I try to cancel they do there best to talk you out of it, they give me another discount or more free products, and you are talking to someone from another country and it is hard to understand. This is why I never do this, I guess I will try again, but I do not like a company that bullies you in to staying. Has anyone else had trouble canceling the membership? Maybe I am too soft and easy just need to be firm! I like the product it is good.
