Dunkin’ is running a limited-time promotion offering 1 million free Refreshers drinks to Dunkin’ Rewards members on August 3. Multiple outlets report that the offer is only available for that day and includes instructions for redeeming the free drink. One source notes that customers can claim the drink by using a specific coupon code during checkout. Another source confirms the same overall structure of the deal, emphasizing the “today only” nature of the giveaway and that it is tied to Rewards membership.

According to the coupon details cited, the code “DUNKINDI3HARDS” is used to redeem the promotion at checkout. The offer is described as valid for five days after redemption, allowing customers a window to pick up the free Refreshers. The promotion is presented as a finite giveaway tied to reaching the 1 million-drink limit, so availability depends on timely redemption.
