Sure you can buy tickets from the comfort of your own home to any of the area's wonderful entertainment, but here's why you should go to the newly opened Northampton Box office...
Lower service fees can make a $10 difference, they only charge you a buck a ticket when you actually go in, I think it is $3 online. Also you get the tickets in your hot little hand right there, and you can get an idea of what other shows are going on around town. Some times they have promotional stuff there too.
This is a big releif to Noho-ers who had to make the trek to the top of thornes during odd hours to get their tickets before.
