Yes. Rewards typically have an expiration period of 1 year, but this can be customized by the buyer.
Depending on the setup, rewards can be valid for anything from 1 month to several years.
Recipients will always be able to see the expiration date clearly in their reward email.
Once a recipient exchanges their reward for a specific gift card, the expiration period is updated according to the terms of the selected brand (for example Adidas, Zalando, etc.).
This new validity period will also be shown on the reward site and in the email containing the chosen gift card.
