We have two options in our large city: a place called Movie Exchange and a chain called Half Price Books (which does buy books, movies, VHS, CDs and even vinyl). First one gives better offers, but is much more selective. Second gives very little (they do sell things for half price or less off, so they can't offer much). Walk out with cash and any discards I feel might still be worth something I take to the local library.
If you live in a reasonable sized town/city, you likely still have something similar.
I don't sell on Craigslist because it's too dangerous in my city (string of armed holdups and even assaults from Craigslist over the stupidest things).
I'm not into selling things online because it's a super hassle for me to go through and price each thing, then print out shipping labels, assemble packing, and drop for mailing. Sounds like too much time for me to waste. Instead, I take in a large bin of books/movies when I know I have other errands in the area. Go browse or sit and read/play on my phone while they cull through to get a price, and then move on to next errand.
