Do CD's/DVD's not have this value anymore? I could CD's being phased out, but DVD's are still entrenched. Maybe with online streaming (Netflix) DVD's too are going away? I would think this would be a lagging indicator though as I can see many storing their DVD's now that streaming is an option.
CD's don't and never really did. If you bring in an early CD (like from the 80s) you can get a nominal amount because CDs were rare then. If you bring in a CD from the last 10-15 years they are nearly worthless. Most shops ended up shredding the extra.
DVDs have a bit of crazy market. Some distributors (Disney and Criterion especially) do a short limited run. The 2nd hand stores rely on these gems in a big box of junk to make profit.
