Hi Tobias,
Thanks for checking out our plugins! You are correct on both counts: Events Calendar Pro and Event Tickets Plus are both $89 for a one year license, which includes support in our premium forums. If you’re interested in any of our other plugins, you might take a look at some of our bundles, which offer discounts for buying multiple products at a time.
We do not currently have a trial period, but we do offer full refunds within 30 days of purchase.
Please let me know if you have any other questions!
Thanks,
Jennifer
