Dunkin’ Has Another Million Free Drinks On The Way

Dunkin’ Diehards is quickly becoming the place to watch for surprise deals from the brand.

The latest tease came through the Instagram broadcast channel and the message was deliberately vague. Dunkin’ told members that there “might” be another million coming on Monday, August 10th, while encouraging fans to keep their notifications turned on.

The exact drink has not been announced yet, so there is still a little mystery surrounding the deal. That also means the August 10th offer should not automatically be called a free coffee or another free Refresher. But I’d say it’s looking more like another Refresher deal. 

Dunkin’ Just Gave Away One Million Refreshers

The timing makes this giveaway even more interesting.

The chain has already used million-drink giveaways several times in 2026. It gave away 1,000,001 free hot or iced coffees on April 1st, followed by another one million free coffees on April 21st and another one million on May 19th.

On Monday, August 3rd, Dunkin’ handed out one million free medium Refreshers in a promotion tied to the launch of Dunkin’ Diehards. The deal was available to Dunkin’ Rewards members, who could use the promo code DUNKINDI3HARDS in the Dunkin’ app to claim a free medium Refresher.

The offer was limited to one per customer and only lasted one day, while the free-drink certificate could be used for five days after it was claimed. Dunkin’ also excluded Dunkin’ Zero Refreshers from the deal.

And now, barely a week later, Dunkin’ is teasing another million. I would say that’s a pretty generous follow-up.

The Code Is Coming To Dunkin’ Diehards

Dunkin’ fans will want to keep an eye on the brand’s Dunkin’ Diehards Instagram broadcast channel on Monday. That’s where the latest promo code is expected to appear.

The channel gives Dunkin’ a direct line to fans who want to hear about deals as soon as they happen. That came in handy during the August 3rd Refresher giveaway, when the code was shared with followers and one million free drinks were available.

The new giveaway looks set to follow the same idea. But remember, one million sounds like a huge number, but they can all disappear very quickly.
