How to make huge profict from a 1000-2000g investiment
Ok, for this guide you will need enough money, and this base investiment will be very big or small depending on what item do you want to use.
I'd Also ask you not to flame me if this has alredy been posted or if this is a common thing, since it's just a share (and i'm bored of the leecher status).
1) Choose an item really used in the game, like primals, netherweave, potions, etc. (eg. I used primal earth/mote of earth due to their low cost and not beeing so many in the ah)
2)Now Buyout ALL of that items in The Auction House, and keep buyoutting ALL or those that go to the ah (eg. I used to surf the net, and press search button every 1.30 minutes)
3)After a couple of hours, spam in trade channel that you are selling that item, but keep buyoutting all thoose that you see in the AH (remember to push up the price, for example, on my realm primal earth were for 4.80 g BO, and i pushed them up to 10, telling those guys that if they wanted, they could buy off ah:P)
4)Now, after 1 day of almost noone ot fthat item on AH, the price should have raised for that few that you see, so i bought those 2/3 lasts items and decided a price, around 4 times the normal one (for primal earth, 22 g)
5) Logically, don't flow the market, just put 20 on ah at time, and when you have just 10 left, put 10 more, in around 1 week, you will have enough golds for your epic mount
SUGGESTION
The best items to sell are Primals, since they are really requested and there are not so many, like netherweave cloth, Pots, etc.
