The company has sold 7.2 million of the slushy drinks since 1966. This year is the 50th anniversary of the Slurpee, which is making the celebration extra sweet.
The convenience stores are giving away small Slurpees of any flavor for free from 11 a.m. to 7 p.m. Monday. Other Slurpee-themed items, like doughnuts, cotton candy and flavored chapstick will also be on sale.
The party doesn’t stop Monday. Anyone who buys seven Slurpee drinks using the 7 Eleven mobile app from June 12 to June 18 will get credits for 11 free Slurpees.
That’s a lot of Slurpee.
