Break out the steins, growlers, and buckets because “Bring Your Own Cup Day is back at 7-Eleven this week.

The convenience store chain is allowing you to serve up a Slurpee in basically anything you want for $1.50 on Friday, May 19 and Saturday, May 20 from 11 am to 7 pm at participating locations.

There are, however, a couple of rules:

• Cup cannot be larger that 10″ in diameter.
• Cup must be food-safe clean.
• Cup must be watertight.
• One cup per person.
• Never feed Gremlins after midnight.

More details here.  Enjoy your Slurpee!
