I fell for the free trail offer and receive a month's supply, the order was placed June 8th and I didn't receive the product until June 14th so 6 days elapsed on my 15 day money back guarantee of the 5.95 I thought but to my surprise it's an $80 hit to my bank account. I thought I was done as there was no place that I seen on the form for auto ship but a month and a half later there's a charge for 85.95, so I called the number listed and could not be connected so I called the number on the Avinol site. I got thru to customer service and after being told for a good 20 minutes they couldn't find my account by using my phone number, name, email address or mailing address she suddenly found it. I told I didn't sign for auto ship and wanted a RMA for return and a refund and she offered me just 50% back and I haven't even received the product yet. Stay away from this offer, I paid with my debit card but somehow they managed to get my banking info and started putting the charge thru my checking account directly. SAVE SOME MONEY YOU CAN BUY IT CHEAPER AT WALMART THIS IS A SCAM TO GET YOUR MONEY!!
