Commodities are needed in bulk by many of the different projects related to the starbase. Each commodity donated will give you 8 fleet credits which does not sound like much but it can add up. Anyone can feel free to get a few fleet credits by donating what they have lying around or even spend some E.C. on the commodities and top off a project to help advance the fleet. Below is a table that should help you save some E.C. by buying those commodities at the cheapest location out there.
