Beat Heat With Free Slurpee

7-Eleven is offering customers a free 7.11-ounce frozen Slurpee drink Monday to help celebrate its 84th birthday.

The free Slurpee offer is available until midnight at participating convenience stores while supplies last. As part of the "Slurpee-bration," some locations will offer in-store specials, music, entertainment, prizes and food samplings.
