Dunkin’ is offering free coffee to 1 million customers through a promotion in its app. The offer lets customers claim a free hot or cold coffee, subject to certain exceptions, and is tied to using a promo code when ordering.

Mint and the New York Post both say the giveaway is first-come, first-served and reaches the first 1 million customers who claim the deal. While both outlets describe the same basic mechanics—app-based claiming with a large customer cap—Mint notes that the promotion covers hot and cold coffees but excludes some items. The New York Post similarly emphasizes the free hot or iced coffee benefit for early claimers, without detailing the specific excluded products.
