Dunkin’ Rewards members have a great freebie to look forward to at the end of the month ☕ On Monday, December 29, Rewards members can score a FREE coffee in any size with a promo code that will be released that day! I’ll be sure to post the promo code once it has been released, so stay tuned!
The offer will be available until the promo code limit is reached! As a bonus, Dunkin’ Rewards members can also grab a FREE donut with any drink purchase on January 2, 2026, while supplies last.
