Every day we see three to five threads about people having money problems. We see an equal number of threads about ways to make money. Most of them focus on farming and there are also quite a few about NM monster camping.
The thing about farming is that for most people its tedious and boring. NM hunting is even worse because it is tedious, nerve racking and may have no payoff at all. Does that mean that I don't think people should make money this way? Of course not. If it works for you, then do it. But this thread is aimed at people who hate farming and hate NM camping.
Every once in a while people will talk about working the AH like the stock market, but to date I have never seen anyone explain exactly how it works. So here goes:
WORKING THE VENDORS
The first way to make money off the AH is to find items that sell for much less at the vendor. A great example is the en-spells for RDM. They sell for 1,500-,3500 at the vendor in Selbina, and frequently go for double to triple that when sold at the AH.
Scrolls are by far the best item to do this with because they are consumable. Every mage will need certain spells, and they can never sell them back at the AH so this elimates some of your competition.
The higher the base value of the scroll the more profit you are likely to make, but the slower it will sell. So in my case I will, for example, buy various bar scrolls in Jeuno and sell them for a modest profit in each of the starting cities. On my main I will sell higher end scrolls in Jeuno that I buy in cities like Selbina or Raboa. The En spells are a great example.
Working vendors is a great way to make profit, but it is also highly competitive. I made great money on bar scrolls for a long time, but eventually the profit margin dropped because more people were doing it. But there are always other scrolls (like poison) that you can do this with!
Remember that when a city is in last place it loses access to many items that are still available elsewhere. Importing things like scrolls will net you a tidy profit.
BUY IN BASTOK, SELL IN WINDY
Buying from vendors is not the only way to use the AH. Things like Conquest items always sell for less in their home city. So if you pick up some low level conquest items from the AH in Bastok you can often double your money if you sell them in Windy. Another great example is things like Warp, Drain and Aspir. You can make great money by doing the quest, but you can make even more by selling it in a city other than the one where you do the quest. For example Drain sells for 20k in Sandy, and 36k in Windy.
SPECULATION
This is the most difficult, but also one of the most rewarding ways to make money off the AH. It takes a lot of forethought, and you also run the rist of being wrong so use this with care.
The process is simple. Buy an item that you think is going to become more valuable, and sit on it til the price goes up.
For example I recently played BRD up to 55th level, and so I took the time to look ahead and see what my spells were going for. I noticed that Mage's Ballad 2 was going for about 30k. I also noticed that I was having a difficult time getting into parties because there were at least 8 BRDs in my level range.
Since each and every one would need Mage's Ballad 2, and there were rarely any for sale it stood to reason that the price would go up. So I bought all the copies of Mage's Ballad that came available. Then waited a week. Sure enough the price leapt up to 80k. So I sold all three of mine for between 70-80k and made around 150k profit.
I sold at the right time, but in the week since then prices have fallen back to 40k. Why? Because other people saw the sudden price change and farmed Mage's Ballad to cash in on it. The supply increased, and since most of the BRDs in that level range had their scroll the demand decreased.
I hope these tips help. Some people may notice that I did not give too many specific examples of items, but that's not because I am protecting any sort of secret. Different items go for different amounts on each server, and you are going to have to find out for yourself where the profit lies.
This whole process takes some getting used to, but with mules I spend 30 minutes each morning setting up auctions and when I come home at night usually net around 50-100k. So give it a try and save yourself countless hours of farming!
