On July 13, from 10 am to 2 pm local time, 25 Dunkin' Donuts restaurants across five U.S. markets will offer a free order of donut fries to the first 100 guests in celebration of National Fry Day. That's a savings of $2 and a great way to counteract any Friday the 13th bad luck (unless you're guest number 101, of course). Each order contains five pieces of buttery croissant-style donut dough tossed in cinnamon sugar and served warm. (We're getting hungry just thinking about it.) Click here to see if there's a participating location near you. If there isn't, well, it is Friday the 13th.
