			With regard to eBay auctions, I think a big reason is that searchers filter out BIN listings. There are so many BIN items that are vastly above market value that it often seems like a waste of time to plow through seemingly endless listings of people hoping to get 3-4 times what an item is worth.
 For me personally, I usually filter out BINs because it is usually a waste of time to view the BINs.
