Getting cheap Broadway tickets

The last few weeks have been tough for Broadway (a few shows have announced closing already in the last couple weeks).  The one upside to this is that it's a lot easier to get cheap show tickets now.  Just about every show is turning up on the TKTS board these days.  Personally, though, I still prefer to use discount codes, since it saves me time.  My latest favorite place to get codes is www.nytix.com, since it pretty much collects all of them in one place.  (They also have some cool content, like theater profiles and 'theater business' articles.)
