Can I refer myself and earn a commission on my own subscription?

You cannot refer yourself, and you will not receive a commission on your own subscriptions. There is also a limit of one commission per referral. If someone referred by you orders multiple subscriptions, then you will receive a commission on the first order only.  Corporate subscriptions that include the enrollment of multiple employees / personnel will count as one subscription, and will be paid accordingly.  For example, if a company subscribes to a plan that enrolls 20 employees, it is considered a single subscription, and a commission will be paid on the entire subscription.
