I really decided to make at least the first week of Cataclysm a farming festival.

I can pick any kind of farming activity, mining, herbs, skinning and also enchant/cloth (as a 5-boxer I can just keep farming the 1st intance over and over again for these materials without having to wait for groups - not to mention getting all the loot ).

I think I'll first go for mining and then will decide how I'll move on.

But my question is, regarding trade material such as ore, plants, leather, cloth, gems and enchants, what prices should we expect for the let's say first 2-3 days?

How should we price the above mentioned items?
For how much should we snatch them?

Thank you in advance for your insights,
