7-Eleven's Share-a-Slurpee event kicks off today (Aug. 13) and runs through Sunday. Customers who buy any size or flavor Slurpee drink at participating 7-Eleven stores nationwide will receive a second Slurpee drink free.

The five-day "Share-A-Slurpee" promotion is a way "to celebrate both the end of summer and the new school year," says Sean Thompson, senior vice president and chief customer officer for 7-Eleven.

Sweet!
