I am indeed referring to high end items. I've been researching markets in prep for a transfer myself. While some things can be close, others can be as much as 6.4x times as expensive...Just among the items I've tracked.

Gilgamesh and Balmung, being the highest population NA servers, tend to have much lower prices for high end items. Anything from IW crafting gear to the latest glamor outfits, and so on. The upside to this is, transferring away from those servers, you can also make quite a bit of profit if you play your cards right.
