I already opend trad with wales, and to help faiclitate you getting you ghoods intot he med sea, i instructed my merchants to actas middle men;
Plexus, you shoudl probabley take a look at all this
-you(wales) make more money, and waste less resources, by selling wool at a reasonable cost to Lisboa
-because i act as a middl eman, your own ships only have to travel to lisboa; and because of my nation acting as a middle man, to the nations of the med sea, there is incresed demand foor wool, which your ships, not having to make journeys all the way into the med sea, can capiloize on by delviering more fleece to the northen nations of europe directlly,and to Lisboa directlly
-In turn, lisboa takes that wool, bought at reaosnable cost, and using its trade ships, plies th emed sea, and North africa, creating a larg emarket for the fine wool product sof wales
-the wool is in turn, sold an incresed (but still reasonable, but still highj enough to turn a good profit from the middle-man venture activites)
-Lisboan ships dont have to bother goign to wales to pick up wool diliveries, and can instead, focus on the exproting of the excess inports of wool to forigen nations(as of course, some woudl be consumed by the Lisboan populace, particurlaey at its cheap cost, for a forign "luxury")
all this combine spells out high profits for both you AND me, while maximizing the effeciency of resources used. After all, as the saying goes "waste not; want not"
