He originally had a 1c undercut, post a wall, post frequently, and post from one toon strategy. However, several competitors entered the market. In response he also put on a 30g ceiling on pricing, in an attempt to discourage competition.
This lasted nearly a week, then he disappeared. I don't know why or where he is gone, but I wish him well.
However with him gone, and having someone else post my glyphs for me - including during the day, I am crafting a lot more glyphs, to the point of occasionally running out. I also note the significant re-entry of other players - including Breevok (who I would like to make a new post soon - maybe on your apprentice series, or even just glyphs).
I know that my competitor had toons on other servers, and probably other tradeskills too, so may be playing elsewhere. Or real life may have interfered. Dominating the glyph market was taking his time - lots of it. Regardless of why, the fact is that dominating the glyph market no longer is worth his time.
What I do know is that dominating a profitable market takes work. I have done it before. The first time I did it I burned out and left the entire glyph market for a month, and defeated my purpose of driving out competition. When I returned to the glyph market, and ever since, I have been careful to play hard, but not play harder than I am prepared to commit.
If you have less time and more demand:
- raise prices (reduce demand profitably),
- outsource work (make more time),
- concentrate on your most profitable items (make more time).
- lower prices (increase demand ),
- do your own work
- diversify (find new markets)
