Low pop server -> low supply -> high prices = mostly caused by resellers High pop server -> higher supply -> mostly lower prices = resellers can't buy everything to relist, especially items which are easily farmed I've used to play on a higher pop server. When I got into the gem market ppl thought they could just buy my cheap stuff and relist. Well, that didn't work out thaaaaaaat well, cause ore supply was pretty much unlimited at reasonable prices (I've bought from ppl who prefered to mine and sell their ore instead of bothering with the gem market, and they liked my reasonable gem prices).
