Does anyone know any other lift ticket or voucher sellers who just told people to shove it, besides SKI Vermont?
I could be wrong & probably am, but AFAIK Ski Vermont is the only entity not honoring things like pre-paid vouchers or pre-paid lift tickets next season, for at least a limited spell (e.g. open to December 20th or March 1st to close). Even some season pass products, which you could certainly make the argument have far less reason to make any concessions at all, are doing so.
Got burned on 3 of them, but at least the one I did use was at Stowe. I'm really surprised by their move to just say too bad. I wonder if they have a way to see how many were remaining at the end of the season. Perhaps they felt there either weren't enough out there to make it worth it OR the vast majority of passes are still out there.
