Donut lovers now have something to look forward to on Fridays, as Dunkin’ (DNKN) is offering free donuts every Friday for the full month of March.

To receive a free donut from Dunkin’, customers need to be a member of the coffee chain’s DD Perks Rewards program. With every beverage purchased on a Friday in March, Dunkin’s will provide a free donut as a reward.

Customers that are not currently DD Perks Rewards members can enroll in the program to get their free donut by downloading the Dunkin’ app or by going to DDPerks.com. Dunkin’ DD Perks Rewards members earn five points for every dollar spent on qualifying purchases with 200 points equaling a free beverage of any size.

The free donut promotion begins Friday and runs every Friday until the end of the month. Customers can select from a variety of donuts, including favorites such as Boston Kreme, Glazed, Strawberry Frosted with Sprinkles, and Glazed Chocolate, to name a few.

In addition, Dunkin’ is offering its March donut – the Lucky Shamrock. And the restaurant is also offering the chance to win free donuts for a year for customers that post an Instagram video or story of their best Thank Goodness It’s Free Donut Friday moment using #FDFSweepstakes and tagging @Dunkin. A winner will be randomly selected each free donut Friday, ending March 26.

The free donut Fridays takes place at participating Dunkin’ restaurants nationwide.

Shares of Dunkin' stock were down 1.46% as of 11:20 a.m. EST on Tuesday.
