Free donuts at Dunkin’ every Friday this month

Dunkin’ is trying to turn TGIF into TGIFDF: Thank goodness it’s Free Donut Friday.

Dunkin’ is giving away a free donut with the purchase of any drink every Friday this month.

You have to be a DD Perks member.

You can enroll on the Dunkin’ app or ddperks.com.

The deal is available at participating restaurants in the US.

Dunkin’ is also running a contest in which four people can win free donuts for a year.
