Today only – in honor of Hero Appreciation Day, Krispy Kreme Donuts is offering up a sweet deal. Buy one dozen donuts, get one dozen glazed donuts for FREE! Want to get those free donuts, but not wanting to eat them all at once? My Grandma gave me a tip last week: donuts can freeze! She told me that she freezes donuts and reheats them in the microwave and that they are just as delicious!
