National Flip Flop Day this year falls on June 15th! To celebrate, Tropical Smooth Café is giving away FREE 24 oz. Jetty Punch Smoothies. Walk into any of 300+ Tropical Smoothie Cafés this Friday from 2pm-7pm wearing sporting your flip flops and receive your FREE smoothie. This promotion is also to raise awareness for Camp Sunshine, which addresses the effects of a life threatening illness on every member of the immediate family. Any time through June 15th, you can make a donation at your local Tropical Smoothie Café. Online donations are also accepted.
