Grab your flip flops and head over to Tropical Smoothie Cafe!
In honor of National Flip Flop Day, the smoothie store is serving up free 24-ounce Jetty Punch smoothies today.
You just have to stop in between 2 p.m. and 7 p.m. wearing flip flops.
There are locations in East Lansing, Fenton, Owosso, and more.
The cafe is asking for donations for Camp Sunshine, a camp for children with life-threatening illnesses and their families.
