you could sell all those dvd(s) for $.25 each and make a ton of $$..
That's my point though - most of those you couldn't sell for $0.25 each, you couldn't sell them at all, they're garbage.
They've got some that will sell for sure, like the Star Trek boxed sets, etc. - but 95% of those DVDs (and CDs, etc.) are garbage that no one wants for free.
