Planet Smoothie, a Petrus Brands company, will celebrate Earth Day, April 22, by providing the first 30 customers at each location with a free, reusable MacDaddy Mug with the purchase of any 32 ounce smoothie.

Planet Smoothie’s MacDaddy Mug program encourages customers to re-use their mug on future visits with a 10 percent discount on refills.

“Planet Smoothie values the importance of offering a solution that works for our customers and helps the planet by reducing our carbon footprint,” says Tra Williams, president of Planet Smoothie.

“Our MacDaddy Mugs are the perfect giveaway for Earth Day because they allow our customers to re-use their mug every time they enjoy a smoothie.”
