A summer tradition is returning to Frisco, as 7-Eleven celebrates its birthday. This year's event is notable, marking the chain's 99th birthday and the 60th anniversary of the Slurpee.

To participate, customers can visit a local 7-Eleven, Speedway, or Stripes store on July 11. On this day, a free small Slurpee will be given away at participating locations while supplies last, with no purchase required.

Further details about the celebration and any additional perks for rewards members are available from the source.
