Dunkin Promo Code: Get a Free Refresher Today (August 2026)

Dunkin' is at it again. After teasing a "million" free drinks through its new Instagram broadcast channel, the chain has confirmed another drop for Monday, August 10, 2026. This time, the code is out, and if you're a Dunkin' Rewards member, you can grab a free medium Refresher—but you'll need to move fast.

The Dunkin' promo code for August 10

Dunkin' told the New York Post that the official code for this wave is FRSHDROP2. Enter it in the Dunkin' app or at checkout to unlock a free medium Refresher. Note that some outlets have reported the code as FRESHDROP2, but the official code is FRSHDROP2; the alternative is likely a typo. Either way, you must be a Dunkin' Rewards member to redeem it.

What is a Dunkin' Refresher?

If you haven't tried one, a Dunkin' Refresher is an iced drink made with green tea or lemonade, mixed with flavors like pineapple, raspberry, or hibiscus. It's a refreshing pick-me-up, especially on a hot August day.

How to get the code and redeem it

The code was announced via Dunkin's new Instagram broadcast channel, 'Dunkin' Diehards'. To join, head to Dunkin's official Instagram page and tap the invite link on their story, or look for the 'dunkin' diehards' link next to a little orange heart under the brand's bio. Once you're in, you'll get direct messages from Dunkin' with codes and surprises.

To redeem:

1. Open the Dunkin' app and make sure you're logged into your Rewards account.
2. Go to the Offers or Rewards section and enter the code FRSHDROP2.
3. Add a medium Refresher to your order and check out—the discount should apply automatically.

Remember, this is a limited-time offer. Only one million codes are available, and it's first-come, first-served. Once they're gone, they're gone.

This is the second drop—and more are coming

This isn't the first time Dunkin' has done this. On August 3, 2026, the chain gave away one million free medium Refreshers through the same channel. The message back then read, "As a thank you for joining dunkin' diehards…between you and me, we might be giving away 1 million free refreshers on Monday August 3rd. Code will drop on Monday…shhhh."

Now they're doubling down. A spokesperson told The Post, "This is just the beginning, Diehards can expect a few more surprises dropping soon, only through the channel." So if you want to catch future drops, joining the broadcast channel is your best bet.

Tips to maximize the offer

• Join the channel now: If you're not already a Diehard, join before the next drop. Dunkin' has hinted at more surprises, and they'll likely be announced there first.
• Set notifications: The channel sends messages directly to your Instagram DMs, but make sure notifications are on so you don't miss the code.
• Be ready at checkout: Codes can expire quickly once the million redemptions are hit. Have the app open and your payment method ready.
• Check your Rewards status: You must be a Rewards member to redeem. If you're not, sign up in the app before the next drop.

Why Dunkin' is doing this

This giveaway is part of the launch of Dunkin' Diehards, a broadcast channel on Instagram that lets the brand send direct texts and photos to followers' DM inboxes. It's a smart way to build a loyal, engaged audience—and giving away free drinks is a surefire way to get people to join.

If you missed today's drop, don't worry. The spokesperson's hint about "a few more surprises" suggests there will be more opportunities soon. Keep your notifications on and your Rewards account ready.
