Ebay.
If you really don't want shit sell it as a lot instead of individuals. If you want to make more, but take forever to do it go individual. When I wanted to get rid of all my PSY cds I put em on Ebay and got like $250 for a lot of 15 or so cds. If you got the original Dark Lotus album with Marz sell that individual or hold onto it since it's no longer being printed. Check what else you may have that is out of print before you put em on there too.
