July 11 every year, the world's number one convenience store celebrates its "birthday."
That's right, 7-Eleven is in its 79th year in business, and to celebrate, participating stores across America will serve 3 million free 7.11-ounce Slurpees in special "Happy Birthday!" cups to customers as long as the cups last.
Better hurry. Who knows how fast 3 millions Slurpees will go!?
