There's still time to get a free pizza today.

Flynn Restaurant Group, the biggest Pizza Hut franchisee in the U.S., is giving away free pizza on Wednesday. 

Flynn Restaurant Group announced a special deal for all Pizza Huts under their ownership. Termed as "Guest Appreciation Day," the deal offers a buy-one-get-one-free offer. When guests purchase a large pizza, they will receive another one-topping large pizza for free.

How do I get free pizza?

To receive a free pizza, order any large menu-priced pizza and use the promo code "FREEPIZZA" for online, call, or in-store orders. Remember, it's limited to one per order, the company said in a news release.

I can only get one topping?

Although the offer is limited to one free pizza per order, the code "FREEPIZZA" can be used multiple times in separate transactions, according to FOX 8. Additional charges apply for pan or stuffed crust, extra toppings and extra cheese.
