Okily dokily - did the fast, pocket calculator math after looking up their 2014 STH plans just now to see what's what. $70 per seat for the home dugout box tier in 2014 per the Nat's site, which nets my $5670 price tag from earlier. In years past, this season included, $60 per ticket would yield $4860, which is exactly what I remember paying now. (The 86 of 4860 resulting in my uncertainty between 4600 and 4800.)
So no new, more expensive tiers or anything of the sort apparently. It's just they went from charging full 81-game STHers in my area $60 per game to $70, in one year. While slightly less than the $1k I was touting earlier, it is still an $810 price hike per seat from one season to the next. Like I said, absolutely more than I was anticipating - a 16⅔% increase year-to-year.
When I turned down the 'lock your plan for five year' offer last year, I figured it would be closer to something like $65 per game, up from $60, meaning from $4860 to $5265 per seat per 81-game season. When you figure most folks have two seats, unlike my 'single loner special', and that's $1620 more for 2014 than they paid for 2013. That's rather painful, although as I had already mentioned, the pricing has remained consistent since 2008…
I guess this is the toll for six seasons without an increase in price, and factoring that into the equation makes the $810 a bit more bearable... I guess...?
