Throw your usual diet out the window this week and enjoy some free donuts (or doughnuts, if that's your preference). In honor of National Doughnut Day 2014, several businesses known for selling the fried-doughy treat are celebrating by giving away its coveted dessert to customers on Friday, June 6. While each business has its own rules and regulations for participating in the annual holiday-- a celebration of the Salvation Army workers or “donut lassies” who delivered donuts to soldiers during WW1-- here is a compilation of the six places you can score a free donut:

Dunkin' Donuts

This Friday the world won’t be just running on Dunkin' Donuts coffee, they will also get a free sugar rush with their morning brew. With the purchase of any beverage, Dunkin' Donuts will be giving away one of its famous donuts to customers on June 6. The offer is while supplies last and is only valid at participation locations.
