I"m guessing but I think prices are too high. I have a chance to buy but decided to pass on it.
In the past, season ticket holders didn't have a choice but to buy all the games. Now that you have a choice, why buy all 4 games when you don't have to.
I also think a lot of the buyers are flippers. Without them more seats will be available.
I see everyone trying to sell them on FB.
Here's the other thing: In 7 hours, after all the games are done tonight, we could know the date and opponent of the first game if the Isles win. There's a HUGE swing with Home Game 1. If the Islanders win, there's a good chance we have a home game on Saturday - traditionally the best day to have a game. If we don't have a game on Saturday, then it's Monday, because the Celtics have the area Friday and Sunday. In the beforetimes, you could have the Bull Gang change over the arena for a Sunday fan doubleheader, but I don't know if that's feasible to do a rush job with the new COVID procedures.
The other thing to consider - if we play the Isles, NBC might be willing to cede to Canada and give TOR/MTL a HNIC time slot, giving us a matinee instead. If we play the Pens, NBC might really want that game on prime time - Nothing But Crosby.
I do think prices are high, but I could be getting "screw you for not renewing even though we didn't give you the playoff tickets we promised you back in 2019-2020" pricing. Seats in my class in the balcony are $147, while they were $111 for Round 2 in the 2018-19 season. Granted, there's 2 years of price increases, the possible belief that there's pent up desire to see hockey, and some interesting opponents if the Pens win (as opposed to the blah that was CBJ).
And the current non-STH sale is...wow, expensive. Almost makes me think of buying tickets just so I could resell them.
