It’s that time of year when the sun is hot and the Slurpee® drinks are free-zing – emphasis on the FREE part. July 11, aka 7/11, is the day that 7-Eleven, Inc., the world’s premier convenience retailer, celebrates its birthday and says “thank you” to its customers with free Slurpee drinks at participating stores. This year’s 7-Eleven® Day marks the company’s 81st birthday. Customers can pour their favorite Slurpee flavor in colorful, 7.11-ounce “Birthday” cups throughout the day, while cup supplies last.
