Tomorrow’s July 11 – or 7/11 – so 7-Eleven stores are celebrating. Come in to your local 7-Eleven anytime that day and receive a free 7.11-oz Slurpee drink. With this sizzling weather, this should be a good one! You can RSVP for the event on Facebook, though it’s not required. You can even print a tiny paper party hat to wear on 7-11 Day.
