Getting a cup from a closed show

I'm pretty sure I have an extra one. Message me, and we'll work something out.

(I collect them too, so no judgments. They're great for my desk at work, since when I inevitably knock them over, I don't destroy all my papers!)

Bottom rack and melted. Is there anyway I could purchase a new one? If I go to the theater even though the show is closed?"

Confirming what others have said that either eBay or Flea Market are your best bets. Even if they haven't moved the cups out of the theatre yet, there would be nobody there right now who could sell you one. And of course once the next show moves in they'll clear out anything that might still be there from the previous show, since storage space at most of the older Broadway houses is extremely tight.
