Love the blog.
I tried one suggestion which was to buy ore and convert it into bars - with the understanding that it is 1-1 transfer unlike other metals of that level.
Well mate, someone on my server is buying a lot of cobalt bars - and I don't know why. It is making me rich however.
Here is the maths:
1. I buy a stack of 20 cobalt ore at roughly 20g
2. I turn it into bars
3. I sell the bars: 5 bars for 19g......... or 76g a stack
4. Some guy logs in and buys the lot a few days later!
5. Got back to the AH and buy all the ore you can and sell it for bars.
It is working well for me, and I have made about 1500 gold in the last two weeks.
Thought you might like to know!
