Not much here. Typically lots of damaged goods and junk other dealers could not sell. Auctions are run by auctioneers that run bids. If enough buyers don't show up, which is quite common, they cancel the auction or only sell off the worse of the worse and reschedule the rest. Fees are very high for sellers, which is part of the reason they don't get much good stuff. Ony up side, autioneers rarely know if they do happen to have a good item so you can get a rare good deal.
