Raleigh-based Dynagraphics began churning out shirts early this morning at its facility on Corporation Parkway.
The company is working through the day to fill thousands of orders.
And workers at the MJ Soffee Plant in Fayetteville worked overnight on championship shirts. The plant started production at the final buzzer.
Soffee is printing 12 different designs, which began shipping out at 6 a.m. this morning.
Some of the first boxes went to Duke's bookstore.
And top off the new merchandise hitting stores, Sports Illustrated is paying tribute to the champs. Duke's John Scheyer is on the cover of this week's edition.
The cover reads: "Back on top: The Blue Devils reign after beating Butler in a barn burner."
Issues hit newsstands Wednesday.
