7-Eleven announces 'Bring your own cup day' for GIANT Slurpees - but there's a catch

SEATTLE — 7-Eleven is kicking off Slurpee season this Saturday with BYO Cup Day. That means you can bring your beakers, goblets, jars or anything else that could be even remotely considered a cup to 7-Eleven and fill it with Slurpee deliciousness.

Between 11 a.m. and 7 p.m. on Saturday, it will cost you $1.49 to fill up a “Slurpee” cup of your choice, regardless of size. However, the cup must fit upright through an in-store display with a with a 10-inch diameter hole. So, no trash cans and inflatable swimming pools are allowed.

This is the first time BYO Cup Day has been held in the United States, although 7-Eleven stores in Australia, Canada, the Philippines and Malaysia have held BYO Cup Days in the past.

Slurpee drinks purchased during BYO Cup Day will count as a punch on 7Rewards, 7-Eleven’s customer loyalty platform. If a customer already has six digital punches on their rewards card, they can redeem their free 7th drink at BYO Cup Day.
