Hey-o! Just in time for warmer weather 7-11 is reminding us why we love Slurpees! Grab your own cup and fill that bad boy up for just $1.50 starting tomorrow May 19th, through Saturday May 20th. Get creative and think big! Because as long as it is under 10″ in diameter, is a food safe container, and water tight you’re good to go! Be sure to share your cup on Instagram or Facebook with the #BYOCUPDAY.
