Dunkin’ Donuts introduced two new fruit flavors to its line of Coolatta frozen slush drinks. Grape and Watermelon Coolatta drinks are now available at participating Dunkin’ Donuts shops throughout New England, New York, and Philadelphia through October 6 for the suggested retail price of $2.79 for a small 16-ounce beverage. In Boston, Dunkin’ Donuts customers can purchase either of the new Coolatta flavors for the special price of $1.99 for a 16-ounce size through August 25.

Other Coolatta flavors include Coffee, Strawberry, Tropicana Orange, and Vanilla Bean, which recently returned to Dunkin’ Donuts shops by popular demand after more than a year.

“Coolatta is the ultimate refreshment for people looking for delicious and affordable ways to stay cool this summer,” says Frances Allen, brand marketing officer for Dunkin’ Donuts. “With the entire frozen beverage lineup, Dunkin’ Donuts continues to be the place for busy people to go to keep themselves running.”
