A free Slurpee is being offered at 7-Eleven, with some outlets reporting that it is part of 7-Eleven Day celebrations. The Slurpee is reportedly turning 60, and to mark the occasion, 7-Eleven is also offering other deals, including a gas discount and a new flavor. Details on how to get a free Slurpee, including any rules or time limits, are available, although it is unclear when the promotion ends.
