Buy one get one free is always a good offer — unless it’s puppies or children, that is — and Theatre 99 just announced their own BOGO promotion for Piccolo Fringe.

If you buy an advance ticket to a Piccolo Fringe event, you’ll receive a free pass to come back to any Theatre 99 improv show between June 14 and Oct. 5. That means if you get three advance tickets to Piccolo Fringe events, you’ll get three free passes to Theatre 99. All you have to do when you present your Fringe tickets at the box office is say the secret phrase, “I dig Theatre 99.”

Piccolo Fringe, part of the Piccolo Spoleto festival, highlights  improv, sketch, play, and musical comedy talent. Featuring 46 shows in 16 days, the 12th year of Piccolo Fringe starts May 25 and continues through June 9.

The festival features a huge variety of performances, like the musical comedy of the Reformed Whores and the Shock T’s, the play The Complete Works of William Shakespeare (abridged), one-man shows like Bursting into Flames, Wanderlust, and Teacher in the House: An Urban Tale of Survival.

And that’s not to mention the improv acts like The Have Nots!, The Upright Citizens Brigade Touring Company, Two Bartenders Walk Into A Bar, and Mary Kay Has a Posse, the sketch act Small Men, and the live comedy storytelling show and podcast RISK! featuring Kevin Allison.

You can order your Piccolo Fringe tickets by calling the Piccolo Spoleto ticket hotline at 1-866-811-4111, stopping by the Charleston Visitor Center at 375 Meeting St., or at the Piccolo Spoleto website.
