Most Western jurisdictions require bankruptcy auctions to be publicly posted somewhere by law, since they are conducted at the behest of the local sheriff / judge. The are commonly posted in the public notice sections of the local community paper, for example. So that one place to start. There is an entire liquidations infrastructure side to the retail economy that most people are not familiar with. Like insurance claims - when a cargo container is in an accident - the insurance companies just pay off a flat fee for the entire container, regardless of the actual damage. Often some or all of the contents are fine, but all of that is now sold off through liquidations as grey market product. Again, it sells off cheap, because it is no longer in the regular retail channel. Another example is leasebacks. Corporate leasing - say laptops again - corps will get a lease for laptops for all of their employees - say 50,000 laptops, for a two year lease. These are not retail sales laptops - they are a special manufacture order, and come in a non retail box, but otherwise are basically identical to the retail laptops because they come off the same assembly line. After two years, all 50,000 laptops are returned to IBM, or whoever, and they are then dumped into the grey market to be sold off as leasebacks. So you see - the liquidations world is not just bankruptcies, rather it encompasses the entire end of life cycle for manufactured products of all kinds, who now need to be sold off for a variety of reasons.
