That is the fastest way to get thousand wow gold at once.
I started doing this when I only had 36gold. On a level 28 character. I in return now have 170 gold. Plus my character is lvl 34 and has most of the best equipment on him.Im sure the level 60's and such think its not that great of an idea. But to me it has made my life a lot easier.
P.S. The funny thing about this is people are always looking what the best prices are going for and if they looted all that item from MOBS they don't really care they will list it for 20 silver under the low prices. In reality that was what made me the money. I love it when people think they are underselling me. But I'm the one buying their cloth and relisting it.
Oh , a lot of people probably thinking this is an easy idea. On my server I probably own 3/4 of the wool listings and have the best prices still. After I make 250 gold I will most likely stop since I dont want to let it get out of hand. Such as never being able to get out of the business do to how much I have invested into wool.
Good Luck and have fun. But as you know, make WOW Gold by yourself needs time and energy, if you don't have much time, I recommend you to buy cheapest wow gold online. That is the fastest way to get thousand wow gold at once
