The glyph market has spawned quite a few of the important modern auction house addons. It's a uniquely challenging market, as there are hundreds of different products, each with their own balance of suppliers, buyers, and materials. The challenges faced by early glyph producers were met by a hodgepodge of fairly complex addons and macros, and only recently have unified solutions began to appear. I remember that at one point, I had addons to:
- Keep track of how many glyphs I had on the AH, in various characters' banks and in their inventories.
- Allow me to queue a list of glyphs and build a materials list (that allowed me to buy the vendor mats with one click).
- Automatically queue enough glyphs in the second addon to assure that I kept stock levels at my desired level.
- Automatically post every glyph I made onto the AH.
