Jamba Juice is waking customers up with a spring morning freebie — no purchase necessary. From 9 a.m. to 11 a.m. April 23, get a FREE juice or small smoothie (12-oz.) — choose from Caribbean Passion, Tropical Greens or Strawberries Wild. (Juice selections vary by store.) No substitutions or upsize options available. Limit four offers per party, per visit — while supplies last. Customers must be present, so no picking one up for a friend or co-worker. Unlike most Jamba Juice promos, no coupon is required. For participating locations, click here.
