It's no big secret that FIDDLER is doing poorly at the box office. My suggestion is that you wait until the day of performance and get your tickets at the TKTS Booth. We had mid-orchestra seats when we bought our tickets that way a few weeks ago.
There are also discount codes available at BROADWAYBOX.COM.
To me it seems foolish to pay full price for a show when discounts for it are available.
