The chain estimates that 9 million free treats will be given away.
“Celebrating our birthday with a free Slurpee drink, the product that is probably most closely associated with 7‑Eleven, is a natural … and fun … way to mark the day,” 7-Eleven vice president of marketing and brand innovation Laura Gordon said in a statement. “7‑Eleven Day is a celebration, not only of our birthday, but, more importantly, of our customers. Ninety years is a big birthday, and our customers are the ones who got us here. By adding Slurpee Week, we have a whole week to say thank-you for their business throughout the year.”
