Each July 11, there's only one place to go: 7-Eleven, where you can get an ice cold — and totally free — Slurpee. Thanks to the store's name, Slurpee Day is probably the only free food day anyone actively remembers. And given the recent temps, it couldn't come at a better time. For this year's holiday, 7-Eleven's featured drink is the new, limited-edition flavor, Cap'n Crunch Berries.
