Bring Your Own Cup Day at 7-Eleven in 2025 is on Saturday, September 13. On this day, customers can bring their own clean, watertight, leak-proof containers that fit under the Slurpee dispenser (within a 10-inch cutout) to fill with any flavor of Slurpee for $1.99 at participating 7-Eleven, Speedway, and Stripes locations. The event is a one-day-only tradition with a limit of one cup per person, and it includes two new Slurpee flavors introduced this year: Powerade Xtra Sour Grape Shocker and Nerds Strawberry Slurpee.
