Their wording is sooo unclear and some pages contradict each other. It looks like they used templates for mutliple uses (renewals, new tickets, post season) and did a really poor job sorting them out. I'm sure the reps are going to have a ton of emails Monday morning...probably won't hear back for a couple of weeks!
That's what I'm afraid of. Would it be too hard to somehow specify the per-game price for the postseason tickets? Other teams manage to do that.
