With Stager you can sell special (discount) tickets at the door and in the ticket shop, which can only be seen after a promotional code has been entered. This works as follows:
Go to Settings - Ticketing - Ticket types and create a new ticket type. Give it a suitable name such as 'promo ticket' and select 'Locked' from the ticket type selection menu.
In the Event - Tickets tab of an event for which you want to set up a promotion, you will see the created ticket under 'Locked Tickets'. Enter the (discount) price and enter a promotional code. The visitor later enters this promotional code in the ticket shop and will then see the locked tickets.
Click 'Edit details' to adjust further sales settings, such as sales period or maximum number of tickets that can be sold per session.
You then distribute this promotional code to potential visitors with the message that they can receive discounted tickets for the event by entering this code.
In the ticket shop, the customer clicks on the event and there they can enter the promotional code received. The locked tickets then become visible.
The promotional code is case sensitive. Also be careful not to accidentally paste a space before or after the code, as this will make it look like the code is not working.
