I went through a bit of a CD liquidation a month or so ago, in order to catch up on bills. The only place that gave me a fair deal (about $3 per disc) was Green Noise Records on Clinton St. However they are pretty selective with the genres they buy.
The most of the rest of my CDs ended up being sold to Music Millennium where I felt like I was being ass-raped (about $0.75 per disc). The guy tried to give me this pity story about how the music resale business was down, and people are just dumping their collections and not buying, and blah blah blah. If it wasn't that I was so desperate for cash, I would have asked him why he was continuing to buy?, since (according to his story) odds are so good that the store will be stuck with my discs (many of which were out of print imports on labels like Bear Family that seem to get a pretty good penny in their store now). After that experience it makes me not want to ever shop there again. I don't hate them, but I think I deserved better treatment. At least pull aside the few discs you want to cherry pick and give me a fair price for them, rather than grab 300 and give me low lump sum and a sob story. It's insulting to treat longtime customers like that.
The truth is right now it's a buyers market. Even when I have priced trying to sell Cds on Ebay or Amazon the sale prices are so low that it's better to avoid the headache and just keep your discs and enjoy them.
