 Today's date is 7-Eleven, which is also the annual free Slurpee Day at 7-Eleven. This year happening in the middle of a heat wave around the country. Customers invited to stop by their local 7-Eleven and help themselves to a sweet, icy Slurpee for free. The 97-year-old company has been pouring free frozen drinks each year on July 11th since 2002. But it's hoping to raise awareness this year of an important cause.
