Hi Jason,
Thanks for contacting us!
Yes: our WooCommerce Tickets product is sold independently of WooCommerce which itself is currently available free of charge on the wordpress.org plugin directory.
Right now licenses are indeed annual in nature and typically we do offer a renewal discount, but as you’ll appreciate I can’t actually guarantee that that will remain the case.
I hope that answers your questions but let me know if I can help with anything else.
Thanks!
