Core Event: One-Million-Coffee Giveaway on September 24
On Thursday, September 24, 2026, Dunkin' launched a limited-time promotion offering a free hot or iced coffee to the first one million customers who entered the promo code JUST4U in the “Offers & Rewards” section of the Dunkin' mobile app. The offer began at 12 p.m. Eastern Time and, according to a company press representative, all codes were redeemed by 2:30 p.m. that day. Each customer could claim only one coffee, and the redemption certificate remained valid for three days after entry. Participation required enrollment in the Dunkin' Rewards program.
Background & Context: L.L.Bean Collaboration and National Coffee Day
The giveaway was part of a partnership between Dunkin' and New England apparel retailer L.L.Bean announced earlier in the week. The collaboration introduced limited-edition merchandise—including a “Birdseye Sweater” cup sleeve, a re-imagined L.L.Bean sweater, a Boat & Tote bag, and a coffee-size tote—available for purchase on September 29, 2026. The partnership also set the stage for a second free-coffee offer on National Coffee Day (Tuesday, September 29), when Rewards members could receive a free medium hot or iced coffee with any purchase through the app. That offer excludes cold brew and hot espresso drinks and is limited to one redemption per member.
