Say cheese!

No, you're not having your picture taken, but in the U.S. there is definitely a good reason to smile Monday: Aside from most people not having to go into work because of the federal Labor Day holiday, Sept. 5 is National Cheese Pizza Day. That means everybody, regardless of age, shouldn't hesitate to indulge in every college student's favorite meal that, according to NBC News, was pioneered in Greece before being fine-tuned and popularized in Italy.

And while it is trendy to reach for your smartphone and hit up one of the many food delivery apps to order the latest fancy artisanal pizza incarnation, you might want to give your wallet a break from putting in some hard work on Labor Day and instead look toward one of national chains of pizzerias. Why? Because they're offering a host of deals, including -- in some instances -- freebies. Check out the below deals, courtesy of Go Banking Rates, Fyvor and the companies themselves).
