Stan’s Donuts & Coffee has announced that it is taking this year’s National Donut Day to a new level. This year, Chicago’s iconic neighborhood donut shop will be offering two days of deals to help customers celebrate.

It starts a day early on Thursday, June 1. On catering orders that day, customers can order a dozen donuts and receive the 13th donut for free. Catering orders require a four-dozen minimum to qualify.

On National Donut Day, Friday, June 2, Stan’s will offer a free glazed cake donut with any purchase.

Stan’s Donuts & Coffee currently has sixteen locations throughout Chicago and the surrounding suburbs (including kiosks at various Mariano’s groceries).
