You Can Fill Pretty Much Anything With Slurpee On 7-Eleven's "Bring Your Own Cup Day"
Better start brainstorming.
It's the most wonderful time of the year for Slurpee fanatics, because Bring Your Own Cup Day is just around the corner.
Das rite. In honor of the 50th anniversary of the Slurpee, you can bring your own drinking vessel to any 7-Eleven location on March 18 or 19 (11 a.m. to 7 p.m.), and, for $1.50, and you can fill that thing up with all the Slurpee it can fit.
