Every summer 7-Eleven stores nationwide celebrate the company's birthday by giving away free Slurpees on July 11, and this year is no exception.

“7-Eleven Day, or free Slurpee Day, gets bigger and more popular every year," Joe DePinto, 7-Eleven's president and CEO, said in a press release. “This year we expect to give away 7 million Slurpee drinks, more than ever before, beating last year’s offer by 2 million."

According to the release, July 11 is the convenience store retailer's 85th birthday, and it's the 45th birthday for its iconic Slurpee drinks.

"But the day is also when we do something special to thank customers for their support and welcome new guests,” DePinto said.

All three Severna Park 7-Eleven locations are participating. They are located at 600 Ritchie Highway on the corner of McKinsey Road, 162 Ritchie Highway in Earleigh Heights Plaza and 497 Jumpers Hole Road on the corner of Benfield Road.
