From someone in the live entertainment industry, one major thing to be aware of is ensuring you are not accidentally looking at a third party site or, worse still, a site that is a complete hoax.
A senate bill has recently been introduced to protect NH ticket buyers:

That is not to say that some venues/events are not ridiculously priced. They are. And it sucks that so many venues use Ticketmaster as their sole online method for purchase. But third party sites that mimic a venue's actual website are a huge problem in our industry and I encourage you to be vigilant while purchasing tickets.
