There is a company ebay system but our store rarely uses it. Too much red tape, item needs to be quite valuable but possibly difficult to sell locally. And you need to send it to a central location anyway.
I've never seen anything sent off for that yet myself.
It's a waste of money wasting time on every little thing, you would never actually sort through everything properly that way and where would you put it all? No space for that.
At least 3 full skips (you would call them dumpsters I guess) get emptied each day. That's just rubbish...stuff is quickly broken down in a basic fashion to squeeze as much as possible in those skips. Like smashing all glass/ceramics, making sure boxes are flattened etc.
