The Deal: One free donut with any purchase.
When: All day, because the Canadians are such a kind folk.
The Deal: One free glazed donut and a small coffee. Looks like everything really is bigger in Texas.
When: Between 5am and 12pm.
The Deal: One free donut with the purchase of any coffee or "Chill Zone" beverage. (To clarify, the Chill Zone means slushies, not a John Grisham novel.)
When: All day.
The Deal: A contest that could land you free Entenmann's donuts for a year, or at least one comped box and some donut plush toys.
When: This started way back in April, and is going through June, but there are 10 separate entry periods you gotta look for. The latest one is running now until June 9th at 11:59pm ET. Only one entry per promotion period, so don't get crazy.
