There's no guarantee there will be fans in the building for next season. Even if there are, if no vaccine is available for COVID, who in their right mind is going to sit in proximity of other fans? No thank you.
The other part of this is Devils management needs to come to grips with is many people simply don't have discretionary income to part with now. My GF and I make very good money, but if either of us lose our jobs, the first thing that would go are the Devils tickets. We got ahead of the curve and gave them up already.
EDIT: And just as I finished this post, my rep called and left a message - the day after I requested my refund.
