Every two years, Krannert Center offers up this opportunity to purchase items from the costume and prop shops, which is kind of awesome. It's an effort clear out the old to make room for the new. If you want to shop early, on September 22nd go between 9 a.m. and noon, and get the best selection. You will need to purchase a ticket for $3, which you can do here. If you go from noon to 1 p.m. there is no ticket necessary, but your options will not be as plentiful.
The sale will take place in the Studio Theatre.
