# frozen_string_literal: true

# PriceCategory is a way to segment prices for an Event.
# By default, each Events have a standard price but you may want, for example, to define a reduced fare for students,
# and another reduced fare for children under 8. Each of these prices are defined in an EventPriceCategory.
# You can choose to use each PriceCategory or not, for each Event you create.
