Bring Your Own Cup Day: Fill 'Er Up At 7-Eleven On Friday, Saturday

CHICAGO, IL — Thirsty for a frosty drink? 7-Eleven is bringing back its popular "Bring Your Own Cup Day," allowing customers to fill up any container (within reason!) with delicious Slurpee at participating locations for just $1.50. This year's #BYOCupDay is actually two days, Friday and Saturday, May 19 and 20. From 11 a.m. to 7 p.m., Slurpee lovers are invited to stop in and fill up their cups with the flavor of their choosing.

But there are rules. According to 7-Eleven, cups cannot be more than 10 inches in diameter, so "trash cans, kitchen sinks and inflatable swimming pools are not eligible." Other rules include the following:

• Cups must be food-safe and clean
• Cups must be watertight
• Only one cup per person on #BYOCupDay

If you don't have a suitable container — or you're really into Slurpees – you can purchase 7-Eleven's blender-shaped, refillable "collossal collectible cup" for $5.99.

Slurpee fans are also encouraged to share their Bring Your Own Cup Day adventures on social media and take advantage of a special #BYOCupDay geo-filter. So happy sipping — just try not to get too carried away.
