Today is Bring Your Own Cup Slurpee Day at 7-Eleven

One of the glorious things about a self-serve drink machine is that you can use it to fill up whatever you want. Still, filling up anything other than a cup from the retail location itself is usually frowned upon.

But not today. For today, 7-Eleven is encouraging its fans to bring whatever they want—“carafes, beakers, goblets, jars”—for its first-ever Bring-Your-Own-Cup Slurpee Day in the United States.

 “Slurpee is all about having fun, and what better way to celebrate warmer weather than by filling your favorite cup with your favorite beverage?” said Laura Gordon, 7‑Eleven vice president of marketing and brand innovation, in a press release from the chain. “From sand buckets to trophies, customers can unleash their creativity by bringing in their choice of a unique, fun Slurpee cup.”

All Bring-Your-Own-Cup Slurpees today are $1.49—but before you dump out the 10-gallon jug from the water cooler at your work’s break room, know that there are limits (probably brought on by enterprising consumers bringing in water cooler jugs and gas cans in previous incarnations abroad):

Still, it’s a chance for Slurpee fans to have some fun, get some cool photo opportunities, and drink a potentially insane amount of Slurpee. What’s not to like? The promotion runs from 11AM to 7PM, so get out there!
