The Whopper is going to celebrate its 64th birthday and to celebrate that milestone, Burger King will be selling the whopper for only 37 cents today and tomorrow, December 4.

This deep discount is available for new and existing Royal Perks members exclusively through the BK mobile app and at BK.com.

This deal's basically like time-traveling back to 1957 and loading up on 37 cent Whoppers. Go ahead and treat yourself.
