BIN is a tough thing from a seller's perspective. I certainly use it - and there have been times that I have absolutely made money by using it. But I don't think it is always so clear.
A) If you have BIN, the BIN disappears after the first straight bid. Ebay is great for starting auctions low - but not so great [IMO] at starting auctions too high. Thus, often a card has a $10 or less opening bid, and the BIN disappears right away.
B) Same as above, but BIN stays if you have a reserve. History has shown that most bidders eschew Ebay reserve auctions.
C) There is always the fear of leaving money on the table. Especially with the run-up in so many pre-war sets lately, what would a proper BIN be? If the seller of the Zeenut Harry Rosenberg or Jimmy Reese cards put a BIN on their auction, they almost certainly would have lost hundreds of dollars. It's always hard to say for sure, of course, but I don't think many people were expecting Harry Rosenberg to go anything close to $1,250. There are dozens of such examples every week on Ebay....
