Love Slurpees? Stop in 7-Eleven May 19-20 to for Bring Your Own Cup Day! Just head to your local 7-Eleven between 11am and 7pm. I participated in this last year and it was great! You’ll be able to bring your own cup or container and fill it up for $1.50! Just make sure it can fit in a 10″ opening, is food safe, and won’t leak! One cup or container per person. Don’t miss out!
