Hi Matt,
Thanks for the interest in our plugins.
Pro and Community Events are different plugins and do not share functions. To get the Community Events features please purchase that plugin and same for Pro.
The only overlap is for Community Events to have Recurring Events enabled is you need Pro as that provides the recurring events functions.
We do not have bundle or special pricing and for nonprofits we have a program to provide plugins for free if the organization qualifies, you can read more about that here.

Let me know if you have any follow up questions.
Thanks
