On aggramar it seems to go painfully slow.
I stood at the ah for some hours with bags full of glyphs (especially the new ones, the ones researched with books of glyph mastery and minors), and made sure I kept my prices waay below the previous lowest priced ones. If the lowest was 270g I would post mine for 190g. And so on.
So far I made 9k gold They just don't seem to sell much or something.
Most of my gold was from selling warbot keys for 1.2k, and selling key to the planes for 500g each.
