"Slurpee Day is our annual celebration of 7-Eleven's birthday and our iconic frozen drink; it's a day of joy, community and good old-fashioned summer fun," said Marissa Jarratt, executive vice president and chief marketing and sustainability officer at 7-Eleven. "We are thrilled to share the nostalgia and create new memories with Children's Miracle Network Hospitals and our customers who cherish this tradition so dearly." Customers can also support Children's Miracle Network Hospitals by opting in to in-store fundraising campaigns starting today at 7-Eleven, Speedway and Stripes stores nationwide. 7-Eleven also released a limited-time Birthday Collection capsule exclusively on 7Collection, the retailer's online merchandise shop. The line features a variety of custom merch and party supplies.
