We all know that when we want to transfer to a different world, there is a limit on the account of Gil that can be taken with the character, 1mil on hand and 100k for each retainer. If we've been on a world for some time, likely we'll amass much more than that so some of us would be in a little bit of a dilemma.

So I'm looking for ideas from people on what items I can buy that i can then sell in the next world without too much of a loss. Of course market prices vary so some things are worth more on some worlds than others so unlikely to ever get the full amount back, but any advice on how/where to spend about 5-6mil Gil would be appreciated.
