Dunkin’ kicked off the season’s freebies by giving away up to 1 million free hot or iced coffees at participating stores between Dec. 29 and Jan. 2, 2026. Customers who downloaded the Dunkin’ app, joined the Dunkin’ Rewards program, and entered the code PRODUNKTIVITY could redeem one free coffee of any size while supplies lasted. The promotion was designed to boost traffic during the post-Christmas, pre-New Year period, historically one of the slowest weeks of the year.
Free Donut With Any Drink Purchase On Jan. 2
The headline offering of the current campaign is a free classic donut with the purchase of any beverage on Friday, Jan. 2, 2026. Dunkin’ confirmed this as part of the week-long ProDUNKtivity Week events, with additional details and redemption instructions shared via social media. This move aims to pair its core beverage business with a sweet incentive that keeps foot traffic strong heading into the new year.
Reusable Tote Bags Added To The Freebie Lineup
In many locations, early customers on Jan. 2 will also receive a free reusable mini tote bag with their free donut and drink purchase. Social media posts from store patrons and Instagram reels show these tote bags being handed out — typically to the first handful of customers while supplies last, with some reports indicating that around the first 200 shoppers could get the branded tote on that day. These totes are sized to carry a donut — a small but visible piece of Dunkin’s merchandise push tied to the promotion.
Merch Sweepstakes Adds Another Layer of Freebies
Beyond the core coffee and donut offers, Dunkin’ also teased a merchandise sweepstakes on Dec. 31 as part of the same promotional sequence. While details about the exact prizes or how to enter have been sparse, previous Dunkin’ campaigns have included branded gear such as mugs, drinkware and apparel, suggesting fans might score free Dunkin’ merchandise through online or social media contests.
Summary: What’s Free, Where, And When
• Free Coffee (Dec. 29–Jan. 2) — One per eligible Rewards member via the mobile app promo code.
• Free Donut (Jan. 2) — With purchase of any drink at participating Dunkin’ shops.
• Free Reusable Tote Bag (Jan. 2) — Given to early customers along with the free donut and beverage, while supplies last.
• Merch Sweepstakes (Dec. 31) — Dunkin’ social channels hint at free branded merchandise prizes.
Taken together, this suite of freebies represents one of Dunkin’s most expansive customer incentives in the early 2026 calendar year, with layered offers that reward both digital engagement and in-store visits.
