FYI, the "Beautiful Margoria Treasure", picked up from a box with a silver key while sailing Margoria, shows a price of 500,000. However, when taking it to a Trade Manager, the price is 150,000. I believe the configured value is wrong. There is already a lower level "treasure" for 100,000 and 500,000 is not really that much anymore.

It is lower in price than stated value because you do not have the nodes connected. 

I was able to see a price of 1,059,004 for the item at Baremi Island.  I happen to have nodes connected to Lima Island, which makes me think Lema Island is "invisibly" connected to the Margoria nodes.  I also noticed the price is approximately the list price as shown on the item in inventory (500,000 in this case) multiplied by the percent in parenthesis behind the "Market Price/Current Value" and the result multiplied again by the  "Distance Bonus".  It was not exact, so maybe there is something else going on.  It would be good to have some indication that the distance bonus and the mark-up are not applied for whatever reason or that those values are negative.  Also, the discount due to the nodes not being connected could be shown.  Maybe show the price with and without the nodes connected.  This would apply to any trading.  It seemed odd that the price was an even 150,000 since this is not normally the case.  I'm assuming there is a cap of no more than 70% reduction in price.  PA does not seem to care much about bartering or trading, though, so I don't expect anything.

If nodes are not connected, the trade item is capped at 30% of its value, and any distance bonus does not apply.
