As it has for the past 13 years, 7-Eleven will celebrate its birthday by giving away millions of small Slurpee drinks on 7-Eleven Day, or July 11. To celebrate 7-Eleven's 88th birthday, participating stores will serve the free frozen drinks from 11 a.m. to 7 p.m. local standard time, Saturday, July 11 (7/11), while supplies last.

But the party doesn't stop there. The world's largest convenience retailer is extending the celebration, from July 12 to 18, with 7Rewards Week. During 7Rewards week, 7Rewards members will receive a free 7-Select food or drink valued under $2 with any 7-Eleven cup purchase (Slurpee, Big Gulp, Coffee and Iced Coffee Chillers).  To receive the free 7Rewards Week offers, customers must have 7-Eleven's free mobile app (available via the App Store or Google Play).

During the 7Rewards promotion, customers can select their choice of free 7-Select products under $2, such as 7-Select-branded gummi candies, salty snacks, bakery items, cookies, ice cream and cold beverages.

"7-Eleven Day is a celebration, not only of our birthday, but more importantly, of our customers," said Laura Gordon, 7-Eleven vice president of marketing and brand innovation. "By adding 7Rewards Week, we have a whole week to say thank-you for their business throughout the year."

7-Select is 7-Eleven's line of private brand products that include snacks, bottled water, desserts and more. 7-Eleven has embarked on a store-wide effort to ensure the best quality and taste for its 7-Select line of products. 7-Eleven is carefully selecting premium ingredients for its 7-Select line, and the more decadent or exotic, the better. Consumers are looking for, and expecting, better quality food and new taste experiences. With 7-Select products, 7-Eleven aims to give them what they want.
