On my site i don't want to display any prices. Prices depend on contracts of the customers. A standard text is written in every event detail to explain this to the customer. "free" or 0 makes it hard to understand by the customers.
You can hide that by changing a setting. Go to Event Booking -> Configuration, looks at Themes tab, and set the config option "Show price for free event" to No . After that, it will be hided !
