Free New Metabolism Boost Smoothie from Smoothie King on March 10, 2020 When You Come in with a Swim Float

It's not even spring yet but Smoothie King is ready for the summer by offering a free 20-oz Metabolism Boost smoothie if you show up on March 10, 2020 with a swim float.

The day also marks the chain's launch of new Metabolism Boost smoothies, which are "designed to boost metabolism and help control appetite."

Metabolism Boost smoothies come in two flavors: Strawberry Pineapple and Mango Ginger. Each features organic veggies, non-GMO fruit, and naturally-derived caffeine to help you "feel fuller and satisfied longer."

In case you're wondering what qualifies as a swim float, Smoothie King offers the following guidance: "a float is any floatation device used in a pool, lake, or ocean. Float must fit through a Smoothie King entrance."
