Whenever July 11 rolls around, it means a sweltering heat wave, a long time until the next holiday off work, and free Slurpees. And every year on this day, 7-Eleven stores celebrate 7/11 by giving you free frozen drinks. This year is also a milestone for the brand, so expect some serious fanfare.

On Tuesday, the convenience chain officially turns 90 years old and it expects to dole out a million Slurpees on the house. On Free Slurpee Day, you can go into any 7-Eleven between 11 a.m. and 7 p.m. and get a free small Slurpee. This year the brand is flaunting a cotton candy flavor that tastes just like the carnival treat — in addition to the usual Wild Cherry and Coca-Cola flavors, and that strange cinnamon-flavored Pepsi Fire.

If that amount of brain freeze isn't enough for you, 7-Eleven is also kicking off Slurpee Week starting on July 12. If you buy seven Slurpees between July 12 and July 18, and also scan your purchases on their mobile app, you'll get 11 Slurpees for free. So get your coworkers or classmates in on the deal and you'll have sugary goodness for a loooooong time.
