Wear Flip Flops & Score a Free Smoothie at Tropical Smoothie Cafe on June 21st

June 21st marks the official start of summer, but few people know it’s also National Flip Flop Day. The peeps over at Tropical Smoothie Cafe are celebrating this awesome coincidence in the tastiest way possible by giving away free 24 oz. Jetty Punch Smoothies tomorrow between 2pm and 7pm. All you have to do is show up wearing flip flops in order to score the freebie, AKA this is an automatic win for everyone living on the West Coast. And if you don’t own a pair, just borrow some from a friend, because delicious smoothies, guys!

The event is also promoting a great cause: All Tropical Smoothie Cafes will be collecting donations for Camp Sunshine, a foundation that helps those affected by life-threatening illnesses and their immediate families.

If you’re not able to make it tomorrow, customers can visit any location now through June 30th to purchase a $1 Paper Flip Flop or a $5 Flip Flop Key Fob to contribute to their fundraising efforts. Donations are also accepted here.
