If you think it is fun now, wait a little while. Everywhere you look the global supply chain is in a mess. We are seeing the consequences of decades of slap-happy decisions made behind rose colored glasses. The entire Automobile industry in a disarray because they cannot get a $5 semi-conductor. Reality is hitting home - you might be able to produce and procure 9,999 parts of a 10,000 part pickup, but that one part in 10,000 which you do not have can shut you down. A "perfect storm" of gigantic proportions have hit the building products markets. The latest addition to the storm is a shortage of polymers (PE, PP, and MEG) due to a variety of reasons. Fires at factories, hurricanes, less raw materials available, factory slowdowns, EPA regulations causing factory problems, covid slowdowns, etc..... Then the problems with the distribution side of things. The way I understand some of the adhesives and such that hold the sheet goods (plywood, osb, particle board, etc....) together are dependent on the polymers. The bean-counters who rule over these industries, have not built in any supply chain resilience. That would cost a penny or two and when you are competing with China ( where they don't care) I guess that penny or two means something.
