No one else noticed that currently transmog isn't realy a great market to flip unless you dabble into salvage crate stuff and very rare stuff? Price from stuff different than that is just lowering because of the increase in players coming back/new players that are starting to farm for gold.

What I do is buy salvaged stuff that I know will be worth 30k or more in future that now go globally for 500g-3000g and resell them for my fixed price of 10-30k gold. This works realy well and holds big profit.
