Dunkin' is giving away free doughnuts in tiny totes. How to get one.

Dunkin's week of deals to help consumers get over the holiday drag is coming to an end on Friday, Jan. 2, with a sweet offer.

The coffee and doughnut chain said on its social media channels it is giving away a free doughnut with any beverage purchase on Jan. 2, with customers getting their free doughnut in a tiny, reusable doughnut tote bag, while supplies last. The offer is valid for one free classic donut with each drink purchase made during the promo period at participating Dunkin' locations, the company said on Instagram.

The donut must be added to the order when ordering in-store or in the Dunkin' app, and the offer is not available on delivery platforms.

Dunkin' wants to make you 'produnktive'

The week of deals, dubbed "proDUNKtivity" week, kicked off with a free coffee offer on Monday, Dec. 29. After that, Dunkin' had merch sweepstakes on Wednesday, Dec. 31.

"It’s our way of helping you power through the final stretch of the year. Honestly, if there was ever a week you deserve a pick-me-up, it’s this one," Dunkin' said on its website. "Keep an eye on our Instagram for more surprise drops to help you stay produnktive this week."
