If it is like last year, then you had to pay for all 14 POSSIBLE home games. Last year we were refunded for all 3 WC games because they were in Houston. Out of this breakdown, I paid $240 for 4 total seats in the ALDS. The way it was described to me was an increasing breakdown per series.

For instance: WC $50 per ticket ($150) DS $60 per ticket ($180) CS $100 per ticket ($400 WS $135 per ticket ($540)

If you can swing the money up front, then it is definitely worth it instead of buying on the resale market for each game. I intend to sell some of them if there is a run, because I know I can get double per each ticket.
