Best LP records find?

:: Back in 2013 I visited a building site, downtown, where an architect asked me to meet him, but since he was late, I took a walk around the block and fond a garage sale store: among old sofas, paintings, tables and chairs there were 2 plastic boxes, with 40-60 Lps, as I started to dig it, I found close to 15-20 LPs from the beloved mid 80's era named 'Rock En Tu Idioma' as this was a 1987-1988 LPs series of bands from Argentina, Spain, Chile, Mexico, etc. all of them look as if they were taken care of with love...the owner, a nice elder man wanted 7-10 USD back then for each one...It took me 3 visits to pick the best of them. Many of those are for sale on eBay or Discogs close to 50-60 USD, and I did sell some of them to buy more stuff there...
Every once in a while I visit the store, but luck has vanished and the owner no longer has LPs for sale: "maybe later, thanks for coming!" he says with a smile.
