You should ask around. With an economy as small as ours total demand can be easy to find. also if something's price is rising, odds are that its in demand. Opposite if the prices are falling.
So like when nstars were at 600+ a piece they were in high demand, but now they aren't in demand very much?
Give it a couple of weeks until the new announcement then they will be expensive as ever...i mean what... Yeah you just have to look at the trend, things come and go quick quickly, Also revolves around the mining resets as well partly.
Yeah, that the basic premise. Just like when andrew added the EXP signs a few months back, as well as re-enabling EXP in the mining world, EXP became a hot commodity (and still is) due to the amount of EXP required to enchant. Basically, if a lot of people need something to make a task easier, the item is generally in higher demand.
