@Ama_Hamada as far as saving your Gil goes you can create an alt on different worlds you are interested in transferring to to scope out the market board and see if anything that currently sells lower on your world sells for higher on a lower population server. In my experience due to less crafters being on low pop worlds some items sell for insane amounts of Gil compared to hi pop worlds and you can often turn a very nice profit. Just to give you an example I once transferred to a JP world and bought a ton of Zu Horns for around 40k a pop and turned around and sold them for nearly 2 million each when I transferred back a few days later. I know this doesn't solve your problem of transferring costing too much in the first place but if you ever do have the funds to transfer this could be a way for you to preserve some Gil.
