Fill it up! It's "Bring Your Own Cup" to 7-Eleven Day!

Have a very large ornate beer stein? a juice pitcher...or a small beach bucket -- anything that resembles a cup?! You can fill it up at 7-Eleven Friday and Saturday for $1.50.

The second annual bring your cup event honors the 50th anniversary of the Slurpee drink.

There are however a few rules...

Whatever "cup" you bring, it must fit through an in-store display with a 10-inch diameter hole.

The cup also cannot be more than 9-inches wide and 11-inches tall...and it can't leak and it must be clean and sanitary.

The rules were developed after the convenience store chain learned just how creative people can be with the word "cup" during last year's #BYOCDay event.
