How will I know when my membership is about to expire? Will I receive renewal information?

The expiration date of your membership is printed on your membership card. COSI will send you a renewal reminder via mail 60 days prior to your expiration.

If you are signed-up to receive COSI’s eNews, you will also receive e-mail reminders. By renewing online you save COSI resources like paper and postage costs.
