I could kick myself! I was looking through Craigslist and found an ad for 6,500 45's for $999; VG+ to NM! All with sleeves! 50's through the 90's, all genres - mostly pop and rock!
That's like
15 cents a piece! And the seller lived about 2 miles away!
I waited until the next day to call the seller up. I was too late - the records were sold that morning.
I should really follow my gut next time and jump when I see opportunities like that.
