Tuesday was 7-Eleven Day, otherwise known as The Ubiquitous Convenience Store Hands Out Free Slurpees Day. But this year, the candy-colored fun doesn’t end there: You can still get your hands on some free icy sugar water at 7-Eleven stores, according to Thrillist. Rejoice: It’s Slurpee Week!

If you buy seven Slurpee drinks anytime between July 12 and July 18, the numbers-obsessed company will give you 11 more free. You have to use the 7-Eleven mobile app to do it, though. Just download the app, sign up for the rewards program, and scan your phone every time you get yourself a Slurp. Once you hit number seven, the app will reload with 11 free Slurpee coupons. If you want to, you can redeem them all at once—which is handy if you're throwing a Slurpee party for your friends.

Though 7-Eleven has been giving out free Slurpees each year since its 75th anniversary in 2002, this year’s extra-long celebration is in honor of the chain’s 90th birthday. (The Slurpee itself is only 51 years old.) Better mark your calendar now for 2027, when the 7-Eleven centennial is bound to include a freakish amount of free Slurpees.
