This has been a big week for free food. First pancakes, then donuts, and now 7-Eleven is looking to out-do all the other deals: on Saturday July 11th, they're giving out free small Slurpees from 11 am to 7 pm—provided they don't run out— as they've done for many years.

While the celebration began as a humble play on words, it's really taken off to be quite an event for the chain. Originally what was just a free small 7.11 ounce Slurpee, became the larger 12-ounce Slurpee in 2013, and then just last year became an entire week of freebies.

While anyone can participate in Free Slurpee Day, no purchase required, the week of freebies isn't quite as generous: to reap the benefits first you'll have to sign up for their 7Rewards membership and download the app. Then, only after purchasing a beverage like a Big Gulp, Slurpee, or coffee, will the free item be redeemable. While that could be a turn-off for some, it may actually be a smart investment to sign up for a 7-Eleven membership right now, if only for the new Slurpee flavors and delivery.
