The best of Goodwill...

What the best audio related item that you have purchased at Goodwill or another similar store?

Today I was at two Goodwills and managed to find a few CDs for $3 each.

One turned out to be excellent. It's a violin concerto by Sony Classics and recorded at Air Studio's. I really enjoyed listening to it this afternoon.

Another was new and was still in the original plastic.

I know this is small beans compared to what some of you have managed to find.
