The Auction House in World of Warcraft is always do great help for WOW money making, and this is a great way to make money without spending any World of Warcraft money on a buy-low, sell-high inventory. Let AH be your storage area and let others worry about paying for auctions.
Scan the Auction House using auctioneer. Save two search settings in auctioneer: Search Bids that profit over 50% and Search Buyouts that profit over 50%. In each category, run your search and sort by the most profit.
If you are looking for the high profit items that easy to sell, remember the criteria they should meet: blue or Purple; Weapon, Armor or Special; Under 40 level requirement or 60 level requirement, for example ignoring items for level 41-59 is a strict policy of mine because not that many users will pay market price for non-twink stuff; High Profit plus low involvement on your part, for example the profit is more than triple; Items that are easy to sell and non-profession based so no recipes.
In the trade chat, go 'WTS [item]' before you buy it. When a person sends you a pst, asking how much, just say, 'how much do you want to pay'. If they offer you more than the item is worth by even 10 WOW gold, just say OK and ask them to meet you. Close the sale, and make sure they will meet you or accept COD (although COD takes too long). Buy the item off Auction House and take it to them. They usually will pay you and you just quadroupled your World of Warcraft gold. If you get enough positive feedback from people but they don't have enough WOW money, just buy the item because you'll likely sell it anyway.
A twist to this is if you are listing things on AH you can actually get people to buy your stuff and try to resell it to you. Simply go: wtb [item that you listed at an outrageous price] 200g. Example: 1. Buy an item at 30g 2. List it on AH at 80g 3. Log, then relog as your alt 4. wtb [item] 124g Convince everyone that messages you that you will buy it if they meet you at a remote location. Then wait for the item to sell off AH as a greedy person attempts to dupe you.
But here is a twist to this, if you are listing things on the Action House, you can actually get people to buy your staff and resell it to you. Simply go: wtb [item that you listed at an outrageous price] 200 WOW gold.
