On East Bay craigslist, there is an ad for a rather common record. It is still easily found in the dollar bins of used record stores across the country. It was released in 1979 and has sold half a million copies in the US alone. It's:
"ABBA - Greatest Hits Vol. 2"
Please look up the east bay seller's ad, then carefully read just how much he's asking for his copy. It's not $15, $20, $30, or even 60 bucks.
