It's National Hamburger Day! Bun Bargains and Freebies From Burger King, Wendy's and More

If you're really hungry, you can eat like a king at BK. The chain is offering multiple specials through their site online, including this whopper of a deal: the Ultimate Bundle gets you 2 Whoppers, 2 Double Cheeseburgers, 2 Original Chicken Sandwiches, 2 10-piece nuggets, 4 small fries, 4 small drinks and 4 cookies for $25. A bit much? You can also stick to a Whopper meal for $5.

Carl's Jr. is offering a buy-one, get-one-for-$1 deal. Learn more on their website.

What's not to love about a little brisket on your burger? Today, you can enjoy their meat-packed Smoked Bacon Brisket Burger for $1 when you buy one at full price.

All orders placed through the chain's app will earn double the points today (members get a $5 reward for every 50 points earned). Additionally, through through August 18, the restaurant is offering a $5 gift certificate with any gift card purchase of $20 or more when you order on their site.

Through June 7, any order made through the Wendy's app will get you a free Spicy Chicken Sandwich or Breakfast Baconator. And you can get both — these are separate offers through the app.
