The Auctioneer Add-On is of great help to figure out what you should be selling your loot for, but if for some reason you don't have it installed, a good rule of thumb is this: post for triple what you paid for it, and everything should sell. My favorites are the recipes that you can buy for 5-10s, because they usually go for at least 1g and you can really clean out.

Go into the dungeons alot. Any World of Warcraft leveling guide will tell you that if you have to grind, kill mobs when doing instances. Form a group with 5 members and invade any of the instances appropriate to your level. 2 runs of an appropriately leveled instance will often make you ding.

Here's why. If you were to add together how much game time you waste Alt+tabbing each and every time and keep track of this amount of time up over the course of say several levels, I bet you would be amazed at the amount of time you consumed.

The Library is another stop in the Scarlet Monastery that often releases a large sum of items and gold for the right solo'er. Your first step is to kill all of the mobs, unless of course you are a rogue and can sneak past them.

Some particular guides include screenshots in order to make things look legitimate, however making incredible screenshots in World of Warcraft is not a difficult thing to do, on the contrary people can open their favorite image editor and modify pictures quite easily.

Buy low, sell high. Download an add-on called Auctioneer. Then survey the auction house for items that are being sold way below their established market value

For those who are not interested in skinning, there are other professions available. Whether the character crafts, harvests, or provides a service, the profession can earn gold.

So you're not a fan of trusting paypal yourself? Well you can always look through their domain age & registrant information. Popular domain registrars allows you to check the ownership of the domain and how long it has been hosted for.

Economy in World of Warcraft and economy in real life is very similar. Some items are very popular and demanded, other items are less popular.

Getting an Auction House yourself is very important. The only work of a player is to keep on checking the mail box and get your mails, recipes, and send the gold he/she gets by putting things in the Auction House. Get a level 1, and run them until the closest largest city in an auction, and put them in the mailbox.
