In celebration of National Coffee Day, Duck Donuts guests can enjoy a free medium hot coffee or cold brew with any purchase in-store or online Sunday, September 29. Guests ordering online can use the code COFFEEDAY24 at checkout to receive the offer, delivery excluded.

Shops serve Duck Donuts’ Signature Blend hot coffee, consisting of rare and exceptional beans primarily sourced from the mountainous Boquet region of Panama. The unique characteristics of this bean are brought out in a medium to dark roast that results in an aromatic coffee with ambrosial fruit notes.

Duck Donuts recently expanded its beverage product line with new lemonade-based drinks. Guests can now enjoy two classic lemonade flavors – original lemonade and strawberry lemonade – as well as two all- new vibrant Refresher flavors – Raspberry Dragonfruit and Citrus Mango Pineapple.
