Trading - Basic Goods & Precious Merchandise, Part II

[continued.]

[The SJ-campaign or any other "sphere"-specific campaign might have
additional items on either list, according to local customs]

 Now, each ware might or might not be available in a specific location,
or port - hence some wares are in demand (imports) while others are in
supply (exports). How much a ware is in demand / supply is described
with a modifier ranging from +5 (major imports) to -5 (major exports)
which is applied to a 3d6-roll on a "Base Price Adjustment"-table when
purchasing or selling goods.

 "Base Price Adjustment" range from 30% to 400% of the listed price of a
given good, depending on whether it's a major export (below 100%) or a
major import (above 100%).

 Furthermore, rolling on the "Base Price Adjustment"-table may also be
modified by any mercantile trading skills a character might posses.

O==(=====>

So, basically one would have to come up with a list of (modified) goods
for a port or site.

BTW, I'm quoting directly from the above mentioned products here; am I
violating something or someone? I hope not, as the system is really
brilliant and hasn't been given the attention it deserves - I've even
gone so far as making a whole compilation on trade & commerce including
navigation, various travel fares & rates, currencies & change, medical
advisory, spells & skills, and even new character classes; unfortunately
it's all OD&D...
