The main tool for any serious gold maker is TradeSkillMaster. It is an addon suite with a desktop application that downloads price data and allows you to create rules for easy crafting, mailing, shopping and posting your items on the auction house. It has a premium service that includes e-mail notifications for great deals and importing great deals as a shopping scan.
Simply put, its about expectations. Transmog is not a get rich quick scheme. You won't wake up the next day to a mailbox full of gold on day one, two or three. For most of us, it will take months to get to a point where we have to refresh our mailbox to get to the rest of the gold. Our expectations are high, and the initial results are rarely ever in the same ballpark. A few days or weeks of less than stellar results and we give up, because we lack patience. If you want/need gold now, transmog is not the solution.
Nov 14 social questions, and a few others Hello! so i played wow 7 years ago, and remember it being really social. People would chat or answer questions. But after restarting a few days ago I've gone from lvl 1 to lvl 23 without getting a single reply to the odd question i've had. i'm not overdoing it or anything.. Do people not use the general chat at all? Is the game more group oriented now? Have i missed some setting? other than that - what does the well rested thing mean, and should I be using 2 pets for my hunter. Thanks for the help! OxfordEichi5 Nov 14

Be warned that players will occasionally list items in the Auction House that are sold by vendors. This typically applies to limited sale quantity items or items in remote, harder to reach locations. Items from Outland that advance certain skills (such as books for training Cooking or First Aid past a skill of 300) are typical. These items are notoriously listed for 2, 3, or even 10 times their vendor purchase-able price. Using an add-on such as Auctioneer Advanced can forewarn you of such a tactic. You should ONLY buy such items if your server is so full and busy that you simply are unable to acquire the item on your own. Otherwise, wait for the vendor to re-stock (usually takes about 20 minutes to 1 hour depending upon the vendor). You'll save yourself a considerable amount of money. See Buying Items from Vendors for Resale below for more on this.

For items that you can gather directly, you have the choice of either going out to gather them yourself or to buy them from the AH. The former adds no cost to your item but requires time and effort, while the latter can be quick and hassle-free. Even should you choose to get the materials yourself, don't forget to add them to your cost — your labor and time should be compensated for, even if just a little.

I do not recommend going for TBC, although I remember Hellfire peninsula to be decent, everything else is rather slow. Instead go for WotLK, Borean Thundra gets you levelled very fast, and then you can head straight for Icecrown at 67, which is also insanely fast, although admittedly has a few elite quests. You can go to Sholazar Basin alternatively. 2 zones should get you 60-80 no problem.

The goblins of the Steamweedle cartel have set up several neutral auction houses about Azeroth. Gadgetzan, Booty Bay, and Everlook all house neutral auction houses. The neutral is useful for making money, as commodities that Alliance players can get easily can be sold at a cheap price to Horde players (or vice versa), and then sold at a higher price at a major city.

While leveling, try to make use of the new Battle of Azeroth experience gem, Insightful Rubellite, which gives you +5% experience. Equipping one of these requires a socket in your gear, so try to hold on to a piece of Legion gear with a socket or acquire one of the Legion Legendary rings since every class has one. Each of the rings includes a socket. You can acquire one of these rings rather easily by doing World Quests in Legion zones and acquiring 1,000 Wakening Essences that can be used to purchase a legendary ring in the Legion version of Dalaran.
New to Patch 8.1 is a new leveling flask called the Draught of Ten Lands which increases all primary and secondary stats by 20 and experience gained by 10%. This effect lasts for one hour and persists through death, similar to other battle flasks. This item can be purchased using a new Patch 8.1 currency called 7th Legion Service Medal or Honorbound Service Medal which can be earned doing the new incursions and Warfront activities. Simple earn these medals on your main character, purchase the flasks, and send them to your other characters. The cost is 10 of the medals.
First of all, the value of transmog is decided by rarity and how they look. Some items like Minenarbeithut der Tiefen or Pendel der Verdammnis (they can drop in Uldaman) are worth millions of gold. They are worth so much, because they have a really small chance to drop. Other items are bought well because they look good. Best example in this case is the Glorious set, its legplates Glorreichen Beinplatte reach a 100.000 Gold value easily.
