Hi Mike,
Thanks for checking out our plugins!
The Events Calendar Pro license does cost $89, and that includes plugin updates and premium support for one year. That means that if you need help getting set up, using the plugin, or run into any issues, we’re there to help!
If you are interested in testing it out, feel free to do so – we offer full refunds within 30 days of purchase if you’re not satisfied with the products. I’d recommend starting with our free The Events Calendar plugin. If you like it and want some additional features like calendar shortcodes, additional fields, photo, map, and week calendar views, and recurring events, Pro could be a great solution for you!
Please let me know if you have any questions!
Thanks,
Jennifer
