I'm getting my finals tickets today, they are slightly more than my season seats...they vary so widely though, there is no one set price obviously...and I have no idea how much the other seats go for in Orlando, just my own...
as far as buying some, in the case of Orlando, season ticket holders get first dibs on seats...they dont open public purchase until this Sunday I believe (first game here is Tuesday the 9th), once they do so you have to buy them up right away, the public seats for the Cavs/Magic series sold out in 5 minutes...I imagine these will go equally as fast, if not faster...
