In dungeons, they drop more money, even gold from time to time, but if you are in a group, which you probly have to be in order to actually kill the elite mobs in dungeons, it gets split among the party members.If you need wow gold or mounts any items , u can place an order on buy4games site ,they are really great.
You kill mobs and players
if you have an enchantment of say, looting I on a sword, the chances are that when you kill a zombie or other mob, you will get more of there drop. say if you kill a skeleton, you will probally get 3 bones and 2 arrows, instead of 2 bones and 1 arrow.

Wool is found off of mid-lower level mobs (level 15ish to level 25ish) in the lower level zones (Barrens, Ashenvale, etc). If you are having trouble with the drop-rate or if you are not high enough level to kill the mobs, then you can try finding some on the auction house in your factions major cities or in the neutral auction houses. It usually can be found there in rather large numbers, although sometimes can be quite expensive.
