If there are two things we love, it’s food and freebies. Combine them, and you’ve got a winner. Free food promotions are everywhere: Dairy Queen offers free cones, Ben & Jerry’s gives away ice cream, Krispy Kreme has free doughnuts, and there are promotions for events like St. Patrick’s Day or March Madness. This new giveaway is similar.
National Proposal Day is on March 20. Dunkin’ celebrates by offering limited-edition “I Dough” ring boxes at participating locations (while supplies last). This deal is available only on March 20, so visit your nearest location to snag a ring box with a Wedding Cake Munchkins donut hole — glazed blueberry with wedding cake sprinkles.
