When you buy their product, there is no returns, even if it is unopened. They promise you a free trial, and then they charge you $89 dollars a month, and keep shipping it to you. You thought you were only trying out a free trial. Next thing you know, you are paying 100 dollars a month for their product. I have learned if you give your credit card there is no free trial for a weight loss product. Avesil may be good, but the way they sell it is not.
