Trading and Trade Goods

The best way to make money in a world where teleportation is as yet a limited science is by trafficking in trade goods between locations. The rules of trading are as follows:

Each town has categories for its items - for example, one might wish to know about Saivignon spices. Roll a d20, subtract ten, and add that percentage to that category's prices. For example, if you roll a 7, spices are 3% less valuable here.
When checking after a delay of multiple days (say, on one's next trip), roll 1d8. On a 1, the value decreases by 1d20%. On a 8, the value increases by 1d20%.
Haggling and purchasing in bulk will generally lower or raise the price by (haggle check -10)%, roughly.
