How do auction houses come up with their bid increments? Last night, I was interested in a card in the Leland's auction, which was at $76 (before juice and shipping). The next increment was $101, and when including the juice, the final price would have been above what I was willing the pay for it. However, at say $89, splitting the difference, I would have placed a bid.
Seems to me the bid increments, in some cases, may dissuade bidders.
