A lot of people new to Goldmaking want a 'Silver bullet', an item they can sell and get rich. The problem is, there is no silver bullet, and heres why:
Cost of mats is different on each server
price items sell for is different on each server
number of people competing on a given market is different on each server
Now the reason these are so important is simple: an item that is profitable for me, that costs me 75g to make and sells for 100g, might cost you 120g and sell for 90g. And if only 7 of something sell in a day, and theres 11 people posting it, you won't make money.
So most of the posts you find here, are telling you
HOW to find your silver bullet, how to
FIND the items you want to sell. And yes, you will have to find it
yourself. What works for me will probably not work for you. I'm not trying to 'save the good stuff for myself'. I'm telling you that you need to find your own niche market. Your niche market will need to fulfill the following criterion:
It costs you less to make/buy than it sells for
There is demand for the item
There are not already too many people selling the item
There are a lot of suggested markets, things that have worked for others that you might try. Markets that are not well served on most servers. Markets with high enough demand to support multiple suppliers. But in the end you will need to see if these things work on
your server.
