Terms & Conditions, expiration of Rewards
You can set a expiration period for each reward. In the configuration settings for emails you can select the period or set it to "none", i.e. rewards do not expire.
With each reward we send the following terms.
"Your reward is for one-time use only; it may not be combined with any other promotional offer, discounted gift card or gift certificate. One valid reward per customer per visit. Terms per website apply."
On the Reward Settings page you can edit the terms and conditions for all emails at once.
