A big problem is I don't know where you are. Shiping to Antartica might run a little high.
i'm from sri lanka
What I do with useless electronics is open them up and harvest as much as I can which includes the ferrite beads, all electrolytic caps etc, put the shell back together again and toss into the bin.
Sometimes I like to write "its been taken already" on a piece of paper and put that inside, then I leave it on top of the bin on collection day.
You don't salvage the gold?
theres not a whole lot in the home appliances that I harvest like radios and usb dongles etc, probably not worth the effort.
