The internet is good for hard to find items, but you have to shop around. I needed a replacement glass lid for an very old corningware dish that is no longer made. Amazon had it for 30, but corningware had it for 8. I could never find it in the outlet store.
I have a 10-year-old VIZIO LCD TV that still runs great, but several of the buttons on the remote wore out.
Last year the idea hit me to check on Amazon. They had several sellers. I found one remote that resembled what I needed and it was labeled as the exact same model number. It was listed for $6 and free shipping.
It was exactly the same and works great with the TV. I like the old TV because it has Picture-in-picture, which new ones don’t have. PiP is excellent when watching events broadcast at the same time.
