Trading Commodities

[yil]

[size=17]
as a member, i'v been playing Discovery 4.85 as a single player. after i locate a high priced commodity, i go down the screen to the locations of the cheapest price for this commodity and visit them. An example would be "gold' at tripoli shipyard omicron, gamma. down the screen are the locations of sixteen places selling the "gold" at the cheapest prices. i've visited all of these locations and no "gold" exists for sale in any of them. such is the case for many of the other commodities, like diamonds, ship's hull panels, engine components, etc.
This took a lot of time and i'm very frustrated and disappointed in the game. can somebody please help me and explain what is going on?

thank you,
yil
