We all know how good 711 slurpee’s taste! So can we really blame people for going crazy at ‘Bring your own up day?’ 711 allowed people to bring their own cups and fill them as much as they wanted for $1.50. The only rules were, “the cup must fit within a 10-inch hole, and be ‘food-safe clean’ and watertight.

During a press release, 711 also released a new flavor.

7-Eleven is taking Slurpee season to the extreme with new Airheads Xtremes Rainbow Berry Slurpee, a sweetly sour flavor combination of your favorite frozen beverage. This new flavor is available now.
