Tomorrow is July 11, or 7/11, which means 7-Eleven is giving away free Slurpees at its stores nationwide. The promotion has been going on for years, and fans expect the freebie, which is part of 7-Eleven's birthday celebration.

This year, 7-Eleven is extending the celebration to include music. Customers will receive codes to buy reduced-price Live Nation concert tickets and many 7-Eleven locations will host concerts.
