For Marty night, the tickets were open to the general public and the game was then announced. So a lot of supply was already out in the market and was bought QUICK once the game was announced. Had that not been the case Marty prices definitely >>>> Elias prices.
For Elias night, the Devils held these tickets tightly, intentionally keeping available tickets low & selling in dribs & drabs, as well as doing the mafia tactic of forcing people to buy game packages to games they dont want to go to, solely so they can buy Elias tickets at below kidney donor prices. They did that for Marty night too, but they didnt hold anywhere near the kind of ticket supply they had for Elias night given for Elias night the Devils knew the date BEFORE tickets were on-sale'd.
Add it up, and the Devils made more on this game than a playoff game, though I question the long-term logic of the tactic of artificially monkeying with the market. Personally, I dont care, it's business, but I know a decent number of people who this pisses off.
