It would be nice to have a price tracker that tracked the recent sold prices instead of listing prices, say within 30 days. This would eliminate any confusion on appropriate pricing and help people see what others have purchased for in recent days, of course there is nothing wrong with people listing at any price, but may help guide and shape the market.

Or an alternative a lowest sold price and highest sold price during a 7 day period. Each item when selected would show the high and low end sales to show everyone participating in the market what people are willing to buy items for.
