Do not even pay by check. I paid by check for the introductory shipment. Received the shipment and sent an email requesting to be removed from membership list. I had not created an on-line account. Several weeks later a shipment showed up via UPS and we had the case returned immediately. I then discovered that they had taken money out of my checking account for that shipment. I will be refunded the money MINUS a return shipping fee and a 15% restocking fee. Crooked company. Avoid at all costs. They do not respond to emails and they do not answer their phone.
