If they are a new player who doesn't know what they have, they may interpret your "uhh" as in their asking price is really high and a lot of times they will drop the price. If they know what they are selling, the fact that they are offering it up in Trade Channel shows that they want to hurry up and sell the item. A lot of times they will reply back to work a deal with you, especially if you are polite with them. People who have a good first impression of you will be more willing to sell the item to you at a very reasonable price. Once you have agreed on the price, if both of you are not close to each other at the moment, ask that person to mail you the item using C.O.D. This will allow you to continue doing whatever it is that you are working on while still being able to get the item. If you have to stop playing to meet that player, that is time … and time is money.
Controlling the Market
Control the market. What I mean by this is instead of undercutting someone else‛s auction so yours is bought first, you could do a Buyout on the other person ‛ s auction. Yes you have to spend money to purchase their item but what this means is that you now have a monopoly of that item in the Auction House. You can put both back up for a higher amount and make a profit on both. I am not saying that you should just go out and buy all items of your same type that you are trying to sell because that doesn‛t always work. What I am saying though is that if there is just 1 or 2 auctions up where you know the Buyout is lower than Market Value, it would be beneficial in that scenario to buy that item and monopolize the market for that item in the Auction House.

Setting up your Auctions
If you do choose to set up either a 2 hour or 8 hour auction, you should make sure that the auction isn‛t going to end at a time like 4am. Ideally, you want your auctions to be running in the evenings and end sometime before Midnight. The reason for this is that servers have the most players online between 6pm and Midnight. While this isn‛t always the case such as during holidays, it does hold true in most cases. This is another advantage of using the 24 hour auctions because they will be covering all hours of the day.
The Darkmoon Faire
This next tip requires that you have a decent amount of starting money. As you are already aware I ‛ m sure, there are different types of cards (Beasts , Warlords , Elementals , and Portals) that make up an entire deck. What you do here is buy whatever remaining cards from the Auction House that you need to make up an entire deck. Just remember that when purchasing the remaining cards you need, to not overpay or that will cut into your profit on the deck. Keep your eyes open and a good deal will show up. Once you have the entire deck, you can put that up for sale at the Auction House and you can make a good 50-75 Gold Profit...just from getting the individual cards and assembling the deck yourself. You can make even more when the The Darkmoon Faire is around because the decks can be sold for Darkmoon Cards which are Epic Trinkets that a lot of players are trying to get.
