So I have a pretty big collection of DVDs that I don't use anymore, and I want to get rid of them. But what's the best place to sell them at? Are they even worth selling anymore? And if so, would a trade shop like CEX be good or somewhere like Amazon or Ebay? Or should I just slyly dump them in friends houses over time?

Don't go to any trade shops if you expect to get more than 20p per DVD.
