How can I buy next period gotowebinar ?

Hi webinarfbk  

It sounds like you want to prepay or change your billing period for the GoToWebinar subscription?  

While the normal behavior of online subscribers would be to renew every 30 days or 1 year, you can call into Customer Support directly to request a billing change that is outside this range:  https://support.goto.com/webinar/help/how-do-i-contact-gotowebinar-customer-support-g2w090151
