There is no one month trial option, in fact we have never offered a trial period of any description. We do however, offer substantial discounts off the subscription standard rate from time to time. If you only want to subscribe for a month that’s fine, you can cancel at any time.
When choosing the monthly option you are requesting that provide the service until you no longer wish it. We used to have a system where people had to sign up each time they wanted a month but we received so many complaints because the passwords expired every month and they had to go through the process again, we changed to continuous authority.
