Skin Logic and Eyetensive Good hook , Good Product BUT poor product info and hidden costs! Santa Ana, Cal 92799 Internet

I was looking for a new skin care product.  This  ad looked like a good deal without spending a lot of money.  I paid for the shipping.  No mention was made about future money needed.  Products arrived with No information about prodaucts or anything.  I started using products and liked them but now what?  I called a telephone number of one of the products and was surprised to hear I owed them money for the FREE trial.  I said to Cancel my {order}. I would return  the products.  They wanted $18.71 for each free trial product.  I said No but I would return their remaining product.  This will cost me more postage.  What a scam!
