Sunday is National Ice Cream Day! Get these sweet deals

PHILADELPHIA -- Sunday is National Ice Cream Day, the kind of holiday we can all scream for.

Ice Cream Day became an official food holiday in 1984.

President Ronald Reagan declared the third Sunday of July as National Ice Cream Day and the month of July as National Ice Cream Month.

You can score freebies and deals from Dairy Queen to Burger King, Friendly's, Baskin Robbins, Insomnia Cookies and more.

While it's not ice cream, it IS a frozen treat. Just a reminder that you can still grab a free Slurpee at 7-Eleven this month through July 31.

And, if you're wondering, the top flavor in the United States? Vanilla, according to the International Dairy Foods Association.
