So i have 525 mining and herbalism, as well as 525 jc and engineering, i normally just sell the elementium ore and whiptail and cinderbloom, but the prices are so low now (like 20g per stack) and i'm wondering if theres another good money making method?
Try to say something useful. This is why enchanting is a must have you de armor n stuff you make with bs,jc then sell the dusts and what not on ah. There prices usually never go down.
You really can't get a good answer to this question that would be specific to your server because every one of them is different. If the Cata ore and herbs are down, as Lickalime mentioned, take your mats and craft them into items to sell. Prospect your ore, craft jewelry, mill your herbs, make dark moon cards/decks and fortune cookies. If these don't sell well, or they are saturated, look into WoLK ore and herbs and then crafted items from those. There is always a market - but it's up to you to do the research.
look, everyone makes money diffrently, and they need to, if everyone was doing the EXACT same thing, then no one would make gold. so what i suggest is find a nitch, and fill it. now as far as *Heres a Step by Step Guide to making a Gazillion Gold* there isnt one, and there has been dozens of threads before this one, that break everything down, so use the search function.
