How much is a coffee refill at Dunkin Donuts?

Unfortunately, I don't have access to real-time information like Dunkin' Donuts' pricing.

Here's why and what you can do:

* Pricing varies: Dunkin' Donuts prices can change depending on location, time of day, and promotions.

* Check your local store: The best way to find out the price of a coffee refill at your local Dunkin' Donuts is to:

* Visit the store: Look at their menu board or ask an employee.

* Check their website: Many Dunkin' Donuts locations have websites where you can view their menus.

* Use their app: The Dunkin' Donuts app often includes updated menus and pricing.

I hope this helps!
