Buy-one-get-one Slurpee promotion at 7-Eleven runs through Aug. 19.

Back by popular demand, 7-Eleven kicks off Share-a-Slurpee fun with a week-long buy one-get one free (BOGO) Slurpee drink event.

Beginning Monday, Aug. 13 and running through Sunday, Aug. 19, customers who buy any size or flavor Slurpee drink at participating 7-Eleven stores nationwide will receive a second Slurpee drink free. Whether you’re packing up for college, need a pick-me-up with your colleague or catching rays by the pool, Slurpee drinks always taste better with a friend.

The current featured Slurpee flavor is the bright blue Cap’n Crunch Crunch Berries, re-created as a delicious frozen treat from one of America’s most beloved cereal brands. Other colorful flavors available at participating stores include Wild Cherry, Blue Raspberry, Pina Colada, Coca-Cola and Slurpee Lite Lemonade. Slurpee flavors vary by store.

During the BOGO Slurpee drink event, both the purchased and free Slurpee drinks count toward the 7Rewards “Buy Six, Get the Seventh Free” drink offer available on the 7-Eleven smartphone.
