I have the answer to every pc...

Your item is worth whatever another player will pay you for it. The End.

Nope... you forgot what the merchant will pay for it if other players don't want it

You Know what, you're right. There is always a player willing to pay your price if you look long enough. Therefore, keep on checking prices.

Can i ask how all these price regions we see now for different object come about? are the ranges officialy made by a-net or just random players.

random players create price. In other words it all boils down to capitalism!!

good ol warm n fuzzy capitalism. One guy is willing to pay at a certain price. The next guy isnt. Creation of competition in prices is then created, and constantly in flux through market demand and competitor sellers.

Take your economics classes yet? enjoy!

I think the market is now built around those stupid, annoying spam bot sellers at LA1. They have so much of the majority of perfect upgrades they can dictate how much they are.
