Season ticket holders just got their 2 ticket buy this morning, and tix are turning up on stub hub. There are some real deals to be had right now, as well as some LOLPricing.
This might be your best shot to get a ticket for the NLDS. If you are going to try and buy playoff tix from giants directly, focus on game 2 & possible 3. Season ticket holders were limited to 2 tickets total for the series, and most just bought game 1 tickets, thinking they had 2 tocket purchases PER GAME. I know I bought game 1 tix and was surprised I could not then buy game 2 tix(Reading comprehension fail!).
Probably better seats available for game 2, come general on sale date.
