Just to provide some recent update. We have been shopping tickets for this show for a bit but figured we wouldn't go because it was too pricey (a few months in advance Dress Circle L seats were $189.50 per part). We were excited when the show announced it was participating for the first time in the BOGO Broadway Week this year, but unfortunately our date was not included in spite of about 50-60% of the seats still being unsold. Well imagine our surprise when 3 weeks out, the $189 tickets were now down to $99 per part. We changed our previous plans and jumped on those thinking that was the best option without doing a lottery. A week later, even better tickets than ours were made available at $99 per part. Then a few days after that, similar tickets to ours dropped to $89 per part. And today (less than a week out), similar tickets to ours are now down to $69 per part. I suppose it isn't news to anyone here, but for me, this constantly changing dynamic pricing (down 65%) from the actual advance box office has been a real eye opener.
I did try calling Ticketmaster to just change my seats to better options that were now for sale at the same/ less than what I paid, but they indicated the Potter producers don't allow it for this show.
Anyhow, FYI for those who come after me........
