Here's How to Start Your Week With Free Coffee at Dunkin'

Dunkin's famous free coffee promotion is back! And just in time to offset the rising cost of the competition's PSL, may we add.

Every Monday this September, the coffee house chain is willing to pick up part of the tab, covering the cost of a medium coffee–whether it's hot or iced is up to you–with any purchase (offer limited to one per member per Monday).

And just like the National Coffee Day promo that ran this time last year and the year prior, Dunkin' rewards members will also be able to redeem the freebie on Friday, Sept. 29, in honor of the unofficial holiday.

The company also confirmed it would be offering a few other deals in the days leading up to National Coffee Day, only valid for rewards members who activate the coupons within the app or online prior to completing their purchase.

For a limited time, customers can score a free order of Dunkin’ hash browns with any order of a breakfast sandwich, enjoy any medium hot or iced latte for just $3–including fall-favorite flavors like pumpkin spice–or the option to rack up an extra 100 bonus points mid-week just by ordering ahead via the Dunkin' app on Wednesdays.

If it wasn't clear already, customers will need to be a member of the Dunkin' rewards program to indulge in any of the current offers. Signing up is free and as a member, you’ll earn points that can be redeemed for free food and drinks, unlock access to exclusive deals and uncover a list of secret menu items.
