Hi, Ben. Thanks for your interest in our plugin suite.
I assume you’re asking about using Event Tickets Plus along with The Events Calendar.
When you add a ticket with a cost of $10, the event will display that the event costs $10. If you add another ticket for $20, it will display “$10-$20”.
We have a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
I hope this info helps. Let me know if you have any follow-up questions.
