Coupons

A percentage or a fixed amount, limited by date, by uses and by ticket type.

In the paid plans Read the manual

A code takes a percentage or a fixed amount off. Limit it by date, by how many times it can be used, or to particular ticket types, so the members’ code cannot be spent on the front row.

The customer types it at the checkout and sees the total change before they pay.
