Slurpee lovers, July 11 is your holiday.

America’s largest convenience store chain turns 90 and is marking the day, which it has dubbed 7-Eleven Day, with a Slurpee giveaway.

Participating 7-Eleven stores nationwide are giving away free small Slurpees from 11 a.m. to 7 p.m. Tuesday while supplies last. Choose from 7-Eleven’s new cotton candy flavor or any other Slurpee flavor.

No coupon is necessary, but be prepared to wait in long lines.

Slurpee fans can get even more free brain freeze-inducing drinks.

Use the 7-Eleven mobile app to buy seven Slurpees July 12 to 18 for Slurpee Week to get 11 free frozen drinks.

The app is available at the Apple App Store or Google Play. After downloading, register to become a 7Rewards member to take advantage of Slurpee Week and earn other freebies.

About 24 hours after you buy your seventh Slurpee, your free drinks should automatically appear in the “Scan and Save” section of the app. The 11 free Slurpee coupons expire Aug. 31 and customers only will be able to redeem one offer per day.

7Rewards isn’t only for Slurpee fans. Use the loyalty program whenever you buy fountain drinks and coffee and every seventh cup is free.

7-Eleven also wants to help customers prepare for a summer of selfies and has new Slurpee Chrome Dome lids available at participating locations.

Fans can post their Slurpee selfie photos using #Slurpfies and tagging @7Eleven on Twitter, Facebook and Instagram and following REALLYSLURPEE on Snapchat. Plus, there’s two new ChapStick Slurpee flavors, Chrome Cotton Candy and Watermelon Lime.
