"That is almost the price you would normally pay for those tickets, and Row E is fifth row! "
Row E is not 5th row, they start with BB-EE, then A, B, etc. Also those are $55 tickets, so it is almost double what you would normally pay. Personally I wouldn't pay that much of a mark-up unless the profit goes to a charity, like BCEFA or Actors Fund.
If you want good seats you can get them a couple days before the show at regular price, or wait on the cancellation line.
