Today through Sept. 2, all Healthy Rewards members can take a fun pumpkin-themed quiz to redeem a free 12 oz. pumpkin smoothie of their choice! This smoothie freebie will be redeemable through Sept. 6 with Smoothie King's Healthy Rewards app.
So you must take the quiz by Sept. 2 and then redeem the coupon freebie by Sept. 6.
Smoothie King also gives out birthday freebies, which you'll qualify for by making an account.
