Kind of hard to know what exactly is an “essential” item. Last week the condensate pump for my furnace stopped working. A condensing furnace produces about a gallon of water an hour while it’s running. I rigged up a storage bin to catch the water and would dump it out manually a few times a day. The size of the bin is limited because the furnace drain is only a few inches off the ground. Keeping my house heated basically depends on that condensate pump. I ordered one on March 12 and it was delivered March 14. There’s probably a very long tail of strange things which are actually relatively crucial components that people depend on being able to order (rather than having spare parts on hand).
