A random idea for B&S: What if there were a cap on the number of price reductions? Three seems like plenty, though the number could be higher if we wanted to be generous. That would force sellers to decide, ultimately, on the lowest acceptable price, rather than allowing them to keep making miniscule reductions to a deliberately overinflated asking price. If an item doesn't move after three reductions, either it's undesirable or the seller is asking an unreasonable amount. Whichever, maybe this isn't the best venue for it.
