The problem with this solution is that I list on multiple sales venues, so logistically speaking, only one can have a BIN or you'll be getting in all kinds of trouble. So if I put a $3500 price on Dan (and I have tried) buyers all run to GD and start lowballing there. Ask Esdiel about this tactic as he's run into it as well.
I was trying to find a happy medium by raising my min-bids across the board, while making sure Dan was the lowest, and it seemed to be working fine and it wasn't a big hassle or a time sink... right up until the last month or so where things have devolved quite significantly. It's almost like an arm's race between buyer and seller, with each constantly tweaking his strategy to keep up the with the other.
And I just need a break from the arm's race so I'm taking a month off. I think it will be an interesting experiment to see if the tire kickers and lowballers get the message, while the serious buyers stay serious.
