Slurpee Double Take: 7-Eleven Brings Back BYOCup Day For 2 Days

DETROIT (WWJ) - It's a sweet deal that has Slurpee fans seeing double.

Convenience-store retailer 7-Eleven is bringing back its Bring Your Own Cup Day for the end of summer. But this time, the special event goes for two days instead of one.

Customers can bring in any size container and fill it with their favorite Slurpee from 11 a.m. to 7 p.m. on Friday Aug. 19 and Saturday Aug. 20. The cost to fill your chosen "cup" at participating stores is $1.50, the average cost of a medium Slurpee drink.

Your container must be leak-proof, safe and sanitary, and fit upright through an in-store display with a 10-inch-diameter hole. That means no trash cans or duffel bags, kiddy pools or kitchen sinks.

"This is Slurpee's 50th birthday year, so everything is bigger, and that includes BYOCup Day," said Laura Gordon, 7-Eleven vice president of marketing, said in a statement. "This year's event is double the days and happening twice as many times. ... We started Slurpee season in the spring with BYOCup days, and we are closing out the summer with a second round."
