A: COSI Memberships were extended for the amount of time that COSI was temporarily closed (from March 13, 2020 to June 3, 2021). That way on June 3, when COSI reopened, you had the same amount of time that was left on your Membership when COSI closed. This also applies to Memberships purchased during COSI’s closure. Membership expiration dates were automatically adjusted.
