Free Medium Iced or Hot coffee on Wednesdays (9/2/2020-12/23/2020) at Dunkin Donuts
Must use DD App to place order - though there is no minimum purchase for this duration.
Note: You may not see it in the 'Offers' section of your DD Perks App. I added a Medium coffee to my order, (nothing else was added) and went to checkout and prior to checking out, saw that the total is $0.00. You can then go the coupons/promo section on the checkout screen to see the full terms.
