where can I sell used music cds?

I'm downsizing my cd collection. I don't know where I can sell 'em though. I've thought about craigslist but I've had in the past people who contact me saying"yes I want it" to whatever I'm selling but when I reply back I get a message saying that the e-mail was deleted. There is 1 music store that I know of that buys them but only 3 problems: 1.they only will take certain genres 2. When I called a few days ago they were overstocked and 3. even if I could sell all and/or some of the cds they only give store credit (pennies on the dollar) and I'd rather have cash. I don't trust ebay either. So HELP! please and if anybody knows of places around the Toledo, oh area that'll take 'em please let me know!
