TSM basics.
First of all and most importantly the AH takes a 25% cut of your gold for all sales.
When you mouse over an item you will get a lot of sales data.
You are only interested in average sold daily.
If an item has an average sold under 1. For instance 0.300.
That means it sells very poorly and might takes weeks or even months to sell.
Things like herbs, they sell in volume. Some are selling upwards of 40k per day.
These will sell nearly instantly after you post them.
Estimated sale price>
Use your head when posting.
Players will post a single herb for 40,000g that normally sells for 10g.
No you won’t get 40k for a single herb.
Use your head when posting.
look at the current price.
How many are posted at that price, and how many sell each day.
If you see a “to good to be true” sale price for an item, look it up yourself to see why it would be fetching such a price.
Canceling…
There is no reason to constantly cancel and relist at a small under cut.
Lets use herbs for example.
When your herbs are selling 40k units per day, you will get the average price when the undercuts sell for less and yours are still listed.
The cheap ones will obviously sell fist, but unless there are 40k cheapo ones( enough to satisfy the average amount sold daily), yours will still sell. Might take a few minutes instead of instantly, but they will sell for the fair average price.
Undercutting…
As I said in the first sentence of this post.
The AH gets 25% of your gold for the sale.
Don’t do it.
Nobody wins a race to bottom.
Post your items at the same as everyone else, or average if its a bulk items like herbs, fish, ore, etc,etc.
If your sale price isn’t vendor sell price+25% you are losing gold by selling them on the AH.
You will make more gold vendoring the items instead.
For example, your item vendors for 100g. You will need to sell it on the AH for at least 125g to get the same price as vendoring it.
These are just basics. Following them I’ve made just over 1.5million selling mostly fish and herbs this expansion.
