How to Claim Dunkin’s Free Coffee

Customers can open the Dunkin’ app and enter the promo code JUST4U in the offers section to receive the free coffee certificate.

The promotion does not include cold brew or extra-large hot coffee. The giveaway is tied to Dunkin’s collaboration with L.L.Bean, which launched at the start of fall.

Dunkin’ and L.L.Bean Fall Collaboration

Dunkin’ and L.L.Bean launched their first collaboration on Sept. 22. The partnership combines Dunkin’s coffee brand with L.L.Bean’s fall-inspired merchandise and includes limited-edition products, giveaways and events.

The collaboration began with a limited-edition Birdseye Sweater Cup Sleeve available with hot or iced coffee purchases at participating Dunkin’ locations while supplies lasted. The collection also includes a full-size pink-and-orange Birdseye Sweater and a Boat and Tote featuring both brands.

The companies are continuing the promotion through National Coffee Day on Sept. 29. Dunkin’ Rewards members will be able to get a free medium hot or iced coffee with any purchase through the Dunkin’ app that day.

More L.L.Bean x Dunkin’ Offers Coming Sept. 29

The collaboration will also introduce an L.L.Bean Coffee Tote for $24.95 on Sept. 29 at 10 a.m. ET through DunkinRunsonMerch.com and at select locations in Maine.

Dunkin’ and L.L.Bean are also taking their Bootmobile across the Northeast during the promotion, with stops at selected Dunkin’ locations where fans can receive gift cards and take part in the fall-themed campaign.

For customers interested in today’s giveaway, the key details are the JUST4U code, the Dunkin’ app and the one-certificate-per-customer limit. Availability is limited to the promotional allocation.
