Credits do expire after a certain amount of time if they go unused. Each merchant sets its own expiration period.
​
We'll remind you before credits expire so you can make sure to redeem them. If you aren't looking to make another purchase, gift them to a friend and make their day (and maybe even introduce them to a new brand).

Every time you earn Catch Cash through Offers, the expiration date on your cumulative Catch Cash rewards resets, giving you more time to redeem your rewards.
