Hear Ye! Hear Ye! Tomorrow is Jamba Kids Day. What does that mean? It means that along with all the other fun and awesome things kids get to do, they also get to have a free smoothie tomorrow. On Saturday July 27, Jamba Juice will be handing out FREE Jamba Kids smoothies from 11am – 4pm at participating Jamba locations. Kids under 8 will receive a free smoothie.
