Market Prices at the auction house are constantly fluctuating, two of the base products of wow gold grinding in the outlands can almost double in value in the space of a few hours. This can leave you kicking yourself if you sold something only for it to appear at twice the price of what you put it on for in an hours time.The auction house isn’t the only way though, sometimes you can sell a large amount of something (10+ stacks) for near the auction house value and without it taking its cut. It is always a good idea before selling anything on the auction house to advertise it in the trade channel for the price even a little more than you where going to put it on the auction house for. You will get a few annoying people offering you ludicrously low amounts, just ignore them and stick to your guns, it will pay when someone wants to buy all you have for more than you were going to sell it for in the first place.
Netherweave Cloth.
This drops nearly everywhere in the outlands, its price varies widely, however on most servers it fluctuates between 4g and 10g, a good time to consider selling this on any server is between 7-8g, it might not be the best price you could get for it, but you wont lose precious wow gold in auction house deposits. The best part is that there is always a high demand for Netherweave Cloth, so can nearly always sell this in the trade channel. To pick up Netherweave Cloth I suggest killing the Trolls in the Warmaul Compound in North West Nagrand, There are plenty of mobs to kill and you generally get 1-3 pieces of netherweave per kill, plus you get some Warmaul Beads, which are excellent for getting your rep up with both Kurenai and the Consortium.
Sunfury Signets & Arcane Tomes
Both these drop very regularly in Shadowmoon Valley, these both go for large amounts in the auction house especially since scryers is currently an overplayed ffaction, so many more people are buying these over the Aldor. You can pick up a lot of these grinding just west of the Scryer town in Shadowmoon Valley, between the two bridges there is a road heading south, there are two paths, one has a huge of the blood elves in groups of three and close together that you need to kill, it may be easier to do this in a group of two or three, however if you are soloing take the path a little further on, up towards Eclipse Point, here the blood elves are spread out, and not in groups, Not only will you pick up silver, netherweave and the two Scryer hand ins for these but you will also notice a high drop rate of greens and even the occasional blue, all these can usually be sold on the auction house or even disenchanted.
