Domino's Pizza is kicking off Pi Day the best way it knows how to: by offering 50 percent off all menu-priced pizza orders placed online for an entire week, beginning today and running through Sunday, March 20.

“Our favorite ‘pi’ is pizza pie, of course, and we wanted to give college basketball fans a special deal during the first week of the tournament games,” says Jenny Fouracre, Domino’s spokesperson. “Basketball fans can now enjoy their favorite pizza combinations at half off when they use Domino’s digital ordering channels.”

College basketball’s tournament month is a busy time for Domino’s, especially near the end of it. Domino’s sold more than 1.8 million pizzas during the 2015 semifinals and championship game night combined—enough to give 25 pizzas to each person walking into the stadium at the final game in Houston this year.

“While college basketball teams across the U.S. prepare and compete for a spot in the finals, Domino’s team members are preparing in their own way,” Fouracre says. “They’re putting on their game faces and gearing up for some busy delivery days.”

The 50 percent off deal is only available on menu-priced pizzas ordered through Domino’s digital ordering channels, which include Domino’s website, as well as the iPad, iPhone, Android, Windows Phone 8, and Kindle Fire apps.
