Not sure if this helps anyone, but just in case...
There are a bunch of upper level, side view seats for the Nassau Coliseum show (6/9) that are now in the $175 range.
I believe these used to be those ~$290 VIP/Silver fan seats and/or at the $329 price point. They certainly weren't $175.
I can't speak to other venues, but this may be happening elsewhere.
Ticketmaster allows for a one-time ticket exchange for tickets of equal or higher value. You do have to pay $5 per seat extra.
