Selling stuff, especially if you're well outside of a major city, is sort of tough. Yard sales don't really bring in the cash and take some work. Most people probably don't want the stuff you don't want and even selling that takes effort.
My example is that I have a pile of laserdiscs that some retro collector probably wants but I'm not going to individually list them on ebay for $3 each. Maybe I'll put the whole package on Facebook for a few hundred and see if someone bites but that's about as far as I'll go.
I do live at the end of a long driveway on a busy road and I've found that a good way to dump old lawn equipment and furniture for free.
Better/more expensive furniture is difficult to sell but also valuable enough to keep.
