HUH? Is this unusual?

I walked into a Salvation Army thriftstore in a small Wisconsin town today,never been there before.
Saw a bin with maybe 50 LP's,browsing through the usual
scratched Dean Martin and Mormom Choir drek when I noticed a large box set near the back.
Turned out to be a 10 record, unopened,unplayed Jap RCA pressing of Rubenstein playin the Chopin Sonatas,Mazurkas etc.
Cost,$2.99 + tax .
