You dough not want to miss out on these frosted freebies.

It’s National Doughnut Day (or Donut Day, if you prefer, although the longer spelling is more grammatically correct), and chains such as Dunkin’ and Krispy Kreme DNUT, -1.41% are dishing discounts and samples to mark the occasion.

Check your local cafe or pastry shop for deals on Friday — if you’re still lucky enough to have a neighborhood doughnut shop, that is. MarketWatch’s Fast Foodist is mourning the demise of the neighborhood doughnut shop known for rolling out fresh doughnuts each morning for just a dollar or two.
