A way of restricting how and when your prices are visible for ticket buyers.
You can restrict a price's visibility by:
Customer Tag
Performance
Amount of Price Band sold
Venue Plan sold
You may want to use this as a version of capacity-based Pricing, i.e. show and/or hide prices when a certain amount of tickets from a Price Band or Venue Plan are sold.
It is also useful for Access prices, as you can restrict a price to a certain Customer Tag.
If you have prices that are performance-specific, e.g. Preview or Peak/Off-Peak prices, then you can use the Performance Tag rule as a way of setting visibility on a certain performance date, day of the week or with a certain tag.
