Have collection of vinyls, cds, dvds and others. Mostly classical, ethnic music (like Spanish, French etc, even one Chinese), complete operas and so on. A lot of them used but also unopened-sealed units. How to sell them to a retailer, as a lot?

You can bring everything to us and we will buy everything that is sale-able. If you want to sell it as a lot, it is a lot of work in that you will need to provide a list of everything and what you want for it.

Thanks for the advise! I called them. "No interest" Will donate the collection to a classical music society. Thanks again!!

They have a wide variety of audio and visual formats to sell. I've seen folks bring in milk crates full of vinyl records. My advice is take your stuff to them and see what they sell and buy.

They may or may not be interested call them

You would have to call them
