I got thousands (to tens of thousands) in hardware for a couple hundred when my local circuit city liquidated a couple years back. Mind you most of this stuff was stuff that wasn't selling otherwise, high current 12V PSUs, huge runs of CAT5 or RG6, cash registers and other POS stuff, etc

The day after it closed they invited me in to take whatever I wanted free before the garbage crew came in, I ended up with a ton (actually a few tons) of random electrical crap, some of which I sold as scrap.
