Ahh, its new patch time again and that means plenty of opportunities to make gold that less observant folks will not have spotted. WoW entrepreneurs know that there are always profits hidden away in those patch notes and 3.1 is no exception. Read them carefully and you will see a few great ways to make fast gold in WoW.
One of things you should always look for is new crafting recipes. Look for those that have highly desirable products and that use mats which are currently cheap or at least affordable.
