What I described is a loophole in the system and its only only helpful for those with sales of less than a certain amount. I think its 80 but I am not sure and when people who have sales far exceeding that do it they have their own reasons that motivate hem.I always thought it was psychological on the part of the seller. If the auction starts just below the BIN, probably a buyer will pull the trigger on the BIN. If a buyer chooses the auction, then the very least the seller will get is the auction start. Never knew about the ebay rules.
