Red Cup Day, the iconic event by Starbucks, is finally back for its customers in 2024. Celebrated across all outlets of Starbucks around the world, the day has become a tradition at the coffee chain since its commencement in 1999.

"Red Cup Day," a favorite Starbucks holiday tradition that offers customers free reusable cups, takes place this week -- but there's a catch.

It is Red Cup Day at coffee giant Starbucks, an unofficial holiday for java fans who enjoy discounts and rewards. Here's how it works: Stop by a participating Starbucks store on Thursday and get a free, 16-ounce holiday-themed reusable red cup when you purchase one of the coffee chain's special seasonal drinks.
