I won't buy other than the real site. Know to many people that got burned. In fact, the last game we attended, we got caught in a line-up because a family had purchased tickets and they were not legit. The people refused to get out of the line, and the employees refused to allow them in.
Many years ago we used to get tickets from dh's boss. He had two sets of season tickets. My favourite were row five with an excellent view of Pat Border's butt. I'm not sure who they played or who won. All I remember is the nice guy sitting beside me who put away his peanuts and ate licorice instead. And Pat Border's butt.
