The local small town appliance store is 3rd generation. Every 3 months or so he puts an ad in the paper saying new load arrived.
First couple times he had every appliance store in the region trying to buy his inventory. Would not do it, for his community. I asked how he gets the appliances, and he said he travels down to several warehouses he's been dealing with for years and buys whatever he can get form cancelled orders or overstock. The thing is some are bottom line and others are top of the line.
He said the warehouses are huge buildings with only one corner being used. Manufacturers are having problem getting stok because it can be only a couple small parts preventing completing the units and the factories shut down because lack of those parts and storage space.
Parts are sourced offshore even those built here.

I bought all new samsung units a couple of years ago and luckily bought insurance on ref. It works fine except it freezes the water line so no ice or water. It has some weird themo thing going on. I had 5 bottles of water next to each other on same shelf and 1 was solid ice and the other 4 had no ice at all. Temp was tested and it was 36. Has to get to over 45 not to freeze.They tired fixing it but finally declared it unrepairable and refunded purchase price so I have new ref. that works great except ice/water for the $300 cost of insurance. I've also had to repair my over stove microwave twice. A $6 part but pain to have to take down to repair. First time I went to work on it I found the 2 tamper proof screws were gone! Turns out HHGreg who was out of business by then sold me a unit that had been tampered with.
