Retailers Dunkin’ Donuts, Starbucks and Krispy Kreme are among those who are tailoring ad campaigns and product specials to coincide with Inauguration-Day celebrations.

Coffee giant Starbucks has teamed with HandsOn Network to launch the “I’m In!” campaign, an initiative to encourage participation in President-elect Obama’s call for national service.

Participating Starbucks stores across the nation will offer consumers the chance to sign up and pledge five hours or more of community service toward a local volunteer opportunity.

People who pledge their time will receive a free tall brewed coffee beginning Wednesday, Jan. 21 through Sunday, Jan. 25. The movement aims to raise pledges in excess of 1 million hours of service throughout the country.

Dunkin’ Donuts, meanwhile, is celebrating Obama’s inauguration with a new “Stars & Stripes” doughnut – a frosted doughnut featuring red, white and blue star-shaped sprinkled. The treat is available at participating stores nationwide for $0.89 from Jan. 17 to Jan. 23.

In celebration of the Inauguration, however, Dunkin’ Donuts is offering the "Stars & Stripes" donut for $0.44 cents with the purchase of a medium hot coffee or hot chocolate (through Jan. 20) at participating shops in Washington, D.C. and other select markets.

Krispy Kreme is also celebrating Inauguration Day by offering a free doughnut of choice to every customer on Jan. 20.

"Krispy Kreme is taking the inaugural festivities nationwide," said Ron Rupocinski, executive chef for Krispy Kreme. "We’re inviting our fans in cities across the country, including Washington, D.C., to commemorate this historic day with a favorite American treat."

The Inauguration Day promotional offer is good for one doughnut of choice per customer on Jan. 20. No purchase is necessary.
