Free Smoothie at Tropical Smoothie Cafe If You're Wearing Flip Flops on June 17, 2016

Apparently, June 17, 2016 is National Flip Flop Day and Tropical Smoothie Cafe will be giving out free 24-oz Jetty Punch Smoothies on the day, from 2 to 7 PM, to anyone wearing flip flops.

While you don't have to buy anything, the smoothie chain will be accepting donations for Camp Sunshine, a year-round camp that hosts children with life-threatening illnesses. Tropical Smoothie Cafe hops to raise $1 million for the charity this year.

The Jetty Punch Smoothie is a strawberry-banana smoothie.
