There's no better way to celebrate the first day of summer than with a refreshing smoothie -- and when it's free, that's just icing on the cake.
Today, Tropical Smoothie Cafe will be giving away free, 24-ounce Jetty Punch Smoothies from 2-7 p.m. to any customer wearing flip-flops in honor of National Flip-Flop Day.
The cafes will be collecting donations for the brand's national charity partner, Camp Sunshine, a camp that supports children with a life-threatening illness. Last year, Tropical Smoothie Cafe gave away about 200,000 smoothies for the cause -- about $1 million in free smoothies.
