Professions
Professions can be very useful during the farming of WoW Gold. There are voices that Mining is best proffesion to get gold - is this true? Well, you can meet very lot copper veins during the travel, and one stack of copper can be sold average for 2g50s, so that way you can get some of the gold. But thats not all - its very good to sell also Iron while nobody is selling it, because you can attack AH with very nasty prices - I sold one stack of Iron Ore for 15g, because there werent ANY other seller- think, that average price of Iron Ore is 25s for one, so its 5g per stack, but I made, to sell it for 3 times more! You should see my face after seeing message „Buyer has been found for your Iron Ore” =) .
I was very happy of it, because I wanted money for the new mount, since now mounts can be bought at the level 30, so you need money pretty fast.
