I just live stories of thrift store scores!
My last was two volumes of the Black Dog Opera Library, Aida and La Boheme, two books, four CD's, all in excellent shape - $4.
Before that, I snagged a Denon DRA-600 receiver for thirty bucks. I saw it there in silver, picked it up, and said to self, you don't really need that...put it down, took two steps...wait, it's a DENON. Ah, it is now the heart of my "main" system, works perfectly, and has a very refined sound.
I admire your LP picks.
