barrysloateJeff articulated it better than I did. There is no ethical boundary crossed, it's just bad form.
People have sometimes come to me asking if I would sell them a special piece from my collection. I often respond I will only do so if they offer a crazy price. That is fine, because it is between the two of us.
But once I put something on ebay or in my catalog auction, there is sort of an unwritten agreement that I am prepared to sell the item for what the market will bear. If that weren't the case, then I should just try to sell it privately.
