7-Eleven’s BYO Slurpee Cup Day Is Here!

It’s here, friends! And by “it,” we mean one of the most magical days of the year. No, not Christmas or your birthday (unless it *is* your birthday, which makes this extra special), but 7-Eleven’s BYO Slurpee Cup Day.

The chain’s BYOC Day is exactly what you think it is. Hop into a 7-Eleven location with your very own travel mug, mason jar, pitcher, or keg (okay, not a keg), and you’ll be allowed to fill it up with your choice of tasty Slurpee goodness.

The convenience store even offered a few handy-dandy instructions to make your Slurpee score a total success.

STEP 1: Bring your custom cup into 7-Eleven on August 18 and/or August 19 between 11am and 7pm.

STEP 2: Fill your cup with as much Slurpee drink as you want for just $1.50. Score!

STEP 3: Share a pic of your cup creation with #BYOCupDay.

The promotion is taking place in the US (excluding Cook County, Illinois), Canada, Australia, Malaysia, and the Philippines, but there are a few rules. All cups must fit upright within a 10-inch hole and be food-safe clean and watertight. Additionally, customers are limited to one cup per person.

Slurpee fans are already getting into the BYO Cup action…
