It might be tedious, but sometimes crafting/vendoring is a good way to make gold. As a JC, one of the two that I do most often is buying zephyrites (on my AH for sometimes 50s) then cutting and vendoring them but the truckload, or making jasper rings which can have a mats cost as low as 2 and vendor for 5.50g.
So are there any other quick-and-boring ways for making gold out there that I (and my fellow crafters) could benefit from? I enjoy watching TV while getting rich.

Forgot another one; If deviate fish are cheap, I can make 'Elixir of Giant Growth' and sell them for 15g each.
