Where can I buy tickets for sold out shows?

I am wondering if anyone can tell me the best place to buy tickets for sold out shows without having to pay too much extra for them. I am searching for Wicked Broadway Tickets in San Antonio since I know that is what my daughter would like for her birthday. Of course she didn’t tell me until the show was sold out, otherwise I would have bought them for her right when they started selling them. Oh well. I am hoping that there are still some available somewhere at a price that I can afford so that I can get her what she wants for her present.
