Price categories carry over for every performance, BUT, the actual prices do not. So, you can use the same price categories for each performance, just change the price and the “print on tickets as” (the day of the performance). The price categories (adult, student, senior, child) remain consistent for the run of a show. That way, the price of an adult ticket for a Thursday performance can be different from the price of a Saturday performance.
The prices and price categories can also be copied from one show to another and from one performance to another. Go to Show | Utilities | Put in categories and prices.
