Dunkin’ is giving away free bat-winged koozies for 1 day only — how to get yours

Dunkin' is offering a limited-time promotion for one day only, giving away free bat-winged koozies with the purchase of a new drink. The promotion kicks off on Friday, October 16, at participating Dunkin' locations while supplies last.

The drink in question is the Berry Battie Daydream Refresher, which debuted on October 14. This refreshing beverage features a Berry Clementine base, offering a sweeter, creamier taste with blueberry flavor and oat milk. To give the drink its spooky Halloween look, it's topped with bright purple Marshmallow Cold Foam and two edible candy eyes.

The pièce de résistance of this drink is the bat-winged koozie. Designed to fit around the cup, the koozie features purple bat wings that extend out from the sides, giving the drink its very own Halloween costume. However, it's important to note that the koozie is only available as part of the purchase of the Berry Battie Daydream Refresher and cannot be obtained as a standalone freebie.
