Dunkin' is giving away 1 million free Refreshers to members of its rewards program starting Monday, continuing what has become a recurring tradition of large-scale giveaways for the coffee and beverage chain. "As a thank you for joining dunkin' diehards... between you and me, we might be giving away 1 million free refreshers on Monday, August 3rd," the announcement read. According to the announcement, Dunkin' Rewards members will be able to claim a free Refresher on Monday, Aug. 3, while supplies last. Dunkin' Refreshers are a category of colorful, non-coffee beverages the chain has built out in recent years, typically combining fruit flavors such as strawberry dragonfruit or mango pineapple with green tea, served over ice. Dunkin' has increasingly used its loyalty program and targeted social media channels, including the newer "dunkin' diehards" broadcast feature, to build stronger direct engagement with its most frequent customers, offering exclusive early access to promotions and giveaways as an incentive for continued participation in the Dunkin' Rewards program.
