I am new here so I am not going to say anything out of line, but some people fail to understand simple things.
The fact is, this site gives sellers the option to list B.I.N or auction but if listing item in auction there is 1 condition...... nobody can see how many different bidders there are or who is bidding which creates problems lack of competition with bidders so lower prices for sellers.
Would you go to a real auction with this rule in place? Don't kid yourself, you want to know who you are bidding against or at least how many bidders there are and that is what makes an auction.
Also when I said about bids helping with pricing items I suppose it depends on what you sell but if you list an item and have no idea of value for a B.I.N there may possibly be a similar item in auction and the amount of bids, current price and finishing price would be useful info to many sellers including me.
