Well... I found a place in downtown Nampa that has been there for some 40+ years... it has a BOATLOAD of old stuff... old books (thousands)... old LP's (thousands)... old 8-tracks (hundreds and hundreds)... old casettes (too many to imagine)... old art... and
Old 45's. I got to take a peek at about 20 of their boxes (each with about 200)... and, get this, the guy claims to have "about 75,000 more down in the basement."
Unfortunately the guy is a hardass on price and won't budge. $2.00 a record... period. Doesn't matter if you buy one of a hundred. $2.00 per record. The only exceptions are damaged/sleeveless which he has a stack of (about 1,000) at $.50 a record but I wouldn't put a needle to them. I ended up picking up about a dozen that I wanted but had to keep from going crazy because they could add up.
I tried to convince the guy to do 25 for $25... wasn' budging. Hell, I tried 15 for $25 and he wouldn't go. I got 13 for $24. The only reason I got the extra was because Foreigner Girl Like You was in pretty bad shape... so he threw it in free.
