Celebrate the 50th birthday of the Slurpee on July 11 at 7-Eleven. From 11 a.m. to 7 p.m., hit up a participating location and treat yourself to the store's iconic icy beverage. 

Each customer gets a free small Slurpee, while supplies last, according to a post on the brand's website. Try a classic flavor or the latest, birthday cake. Find a location at 7-eleven.com.

And if you miss the July 11 celebrations, it's Slurpee Week through July 18. But that's only for customers in the 7-Eleven Rewards program.
