National Doughnut Day deals on Friday

It's National Doughnut Day!

Observation of this day dates back to 1938. That's when the Salvation Army created it to honor women who volunteered with the organization during World War I.

These "Salvation Army Lassies" served donuts to soldiers on the front lines in Europe more than 100 years ago starting in 1917. They often cooked the treats in hot oil inside the metal helmets of U.S. soldiers. As a result, American infantry men at the time were commonly called "Dough Boys."

If you want to celebrate the day, here are some deals.

LaMar's will be giving away free donuts to everyone who visits a store. If you buy a dozen donuts on top of the free one, you will also get a free cup of coffee. Donation bell ringers will be posted at participating locations to raise money for The Salvation Army youth programs.

Russ's will celebrate the holiday by donating $.05 for each glazed or ice raised donut sold from 6-11 a.m. to the Salvation Army. Donut lovers get a deal too, with fresh glazed donuts on sale, three for $1.

Super Saver stores will offer one free glazed donut to the first 200 customers at each store beginning at 7 a.m. on Friday, June 7. Each Super Saver store will also have a Friday only special on a dozen donuts.
