Good evening Matthew and welcome back!
Thank you for reaching out to us.
I would love to help you with this topic.
Does Event Tickets Plus over ride the original price field?
That is correct. This is done to prevent confusion in pricing.
You could apply the following snippet in the functions.php file of your theme (without the PHP tag at the top): https://gist.github.com/GeoffEW/69f8a033fb614c78b3de45a197431135
This will reinstate the field and its use to display the cost.
Let me know how that goes.
Best regards,
Geoff B.
