Donuts have proven most useful to humanity as a breakfast treat, since they are too soft to serve as wheels and too enticing to serve as life preservers. Engage a donut in its most utilitarian mission with today’s Groupon: for $6, you get a $10 Dunkin’ Card for donuts, coffee, and breakfast fare at Dunkin’ Donuts. Dunkin’ Cards will be mailed to the address you enter at checkout. Cards offer a convenient way to pay for all of your Dunkin’ favorites and are accepted at participating Dunkin’ Donuts restaurants. Pricing varies by location.

Dunkin’ Donuts swiftly dispatches early-morning appetites with a menu of awakening items served all day, including fresh donuts, made-to-order breakfast sandwiches, and hot or iced coffee and lattes. Though commuters can snag a quick pick-me-up within minutes, the wafting aromas of baking confections invite patrons to sit inside and embark on nostalgic reminiscences of syrup-coated playground slides.
