I have been noticing on my server alot of the Transmog pieces are selling for 1K. I am thinking of sitting down one day and farming some SM for 2-3 hours to get alot of low level transmog pieces. Even if I don't sell them at 1K each I could probably rake in 3-5K with ease.

Normally I just shard my old PVP epics and then sell mats or enchants on the AH.
