National Hamburger Day is Wednesday, May 28, in California and many burger spots like Burger King, Shake Shack, and Smashburger have specials.

On May 28, Burger King Royal Perks loyalty program members can get a free hamburger with the purchase of $1 or more. Royal Perks members can also get a hamburger for 125 crowns (half the usual reward redemption cost) through the end of May.

Get ready for hot buns and cool prices! Thinking of firing up the grill this summer? Well, think again, and maybe consider what Burger King has in store for you this coming June. The chain just dropped a lineup of mouthwatering fast food deals that feature both flame-grilled classics and cool savings.
