(Please note all costs are in USD):

For the 6-month subscription, there is no trial period, and it's a one-time payment of $147. (There is a saving of $12.50/mo compared to paying the monthly $37/mo for 6 months.) 
There is no trial with this. If this option is what you prefer, click HERE, then scroll to the Buy Now button near the BOTTOM of the page and you'll see a link just below it. Click on that and you'll get the 6 month access for $147.
After the 6 months, your access will automatically expire. You can always extend it if you want by sending a request to support@theonlinedogtrainer.freshdesk.com

For a recurring monthly membership subscription, there is a $1 payment for the first 3 days of access, which is a trial period to have a look around and see if it's right for you. Then if you decide to stay on, there is a $37 payment every 30 days to keep the subscription going. You are always free to cancel at ANY time. There is no contract or any other hidden fees. To cancel all you need to do is send us an email to support@theonlinedogtrainer.freshdesk.com
