It would make sense, lots of builders, supply and demand out of balance.
I don't think its the end of "the big wood era", just a lot of supply of plugs that are not made by the "the hot in demand builder".
Builders with a certain style, niche, type of plug who make a limited supply are still in demand.
Look at the demand for the Super Strike plug colors that are not being made this year, limit the supply, and the demand spikes.
