Go to “Manage Offers > Ticket validity”. The expiration date of your gift vouchers and value vouchers is defined there.
You can define the expiration date of your discount codes in “Discount codes”.
The redemption period refers to when customers place the order. For example, if you choose a date seven days from today for the redemption period, the customer must place the order within the next week to redeem this discount code, regardless of when the activity will take place.
The event period defines the time when the activity must take place. For example, you can set the redemption period until the end of the current month, but then define an event period that specifies that the discount code applies only to activities that take place during the following month.
