This isn't a cheap hobby like years ago. Hopefully things will calm down a bit but I'm not sure if easy to find cheap deals will ever be "normal" again.
There was already a growing problem with sellers driving up prices on all sorts of platforms before covid but it seems to be worse now.
Only way to get good deals is to watch things like a hawk and snap up a bargain when someone lists something cheap (and will consider offers) because they're desperate for money and pawn shops etc won't give them more than pocket change.
