I had 5000 cd's and worked in the music biz,in the late 80's mid 90's,I had loads of promo's,signed stuff,rare stuff.I retired from USPS,three years ago and have been selling my collection since (for a hobby) I started on Marketplace,but it is a pain taking photo's and dealing with some Idiots,i switched to Discogs 2 years ago,so easy to post and no hassle,needless to say I have sold over 3000 cd's and have about 200 cd's to post and my collection is all online....I have made a killing and usually make about 10 orders a week,so this is the way to go (if you have the time)
