No! Once you redeem a reward, there are a few ways to access it if you're unable to use it right away (like if you haven't met the order minimum or cannot combine the reward with a current promotion).
Any reward you've redeemed but not used is accessible in the rewards portal. Simply login, open the rewards widget in the lower left corner of the screen, and click "my rewards"—your discount codes will be saved there for one year from issue date.
We also send you a reminder email with your discount each time you redeem a new reward.
