I stopped tracking the increases in my plywood costs here in London once they'd breached 250% over a two year or so period, starting somewhere around the beginnings of Covid (so, not entirely wedded to lockdown issues, if memory serves). I'll welcome price decreases, but it did make me seek out a new, better supplier so hopefully 'worth it' in the end (I pass on all material costs to clients, so as long as I explain the cost increases, it doesn't really affect me.. it is galling though).
