We too ordered a $4.95 sample, with no warning (or not one a normal person would read) that we had signed up for a $85.95 per MONTH subscription. I was able to cancel the subscription, but not before the first $85.95 shipment went out. CSR "Tay" offered me a 35% credit, but they cannot accept returns. It was a $56 lesson in reading ALL the fine prnt.
The product doesn't work, but at least it causes no harm.
