I just wanted to get the sample product to try for $2.79. The sample came fine but I began to suspect that I had inadvertently signed up for some monthly delivery of this product at a charge of $75 or so. I was not aware that this was what I was going to be faced with when I ordered the sample. Caught it in time so that I didn't get charged for a shipment for the next month.

Their website is not clear on what will happen in the long run. I didn't sign-up for a monthly shipment but they just signed me up without my permission or knowledge.
