Crumbl Silver Members Get a Free Cookie on Their Birthday
Crumbl Rewards members at the Silver tier can celebrate their big day with a Free Single voucher - one free single cookie or dessert to use on their birthday.
Crumbl Rewards membership itself is free, but be aware of the catch: the birthday voucher is listed under the Silver tier, which unlocks at 500 Crumbs earned in the year, and Crumbs are earned on purchases. That works out to roughly $50 of spend at the base earn rate, so purchases are effectively required to reach the tier that carries this birthday freebie.
