That's the way to do it. People throw away so many things that can be still used or sold to someone who could use them.
My father has the best hookup. He knows the guy at the local landfill so he always goes down there. We are from sort of a "rich" town, but we aren't rich by any means. It's a summer town basically so you get all the millionaires and stuff.
But he will find stuff thrown away still in the box, no problems or if anything a minor one. That is how he got a couple big screen tvs. Minor issue that needed to be fixed, but person tossing couldn't be bothered.
He's even given me stuff to try to sell and I've had luck with it.
It's just like myself here in the city. I toss something on the curb and within the rest of the day it's gone. People have a nature to just pick up what could still be good. If you can make $ off it, the better it is. Nice way to save some extra cash, rather than toss something straight out, see if you can Craigslist it or something.
