One of the things I do on heavily camped markets (for example, a suspected bot has been camping glyphs on my server for months) is set my bid price to much, much lower than my buyout (but-- in the glyph market-- still high enough to make some profit, although not compensating for the research investment.) Then I post my auctions at a fair price and walk away.

Most people will have their bid close to or equal to their buyout, and the default AH UI sorts by bid price. However, most buyers will choose to buyout instead of bidding and waiting and won't care that Botter is selling for 2c less. The end result is that I can post my glyphs for 48 hours, come back in 2 days, and still sell a decent chunk [1] of them, with only 3-5 buyouts per cycle. While Botter undercuts my buyout within the hour-- and usually within 10 minutes-- the tools she uses aren't smart enough to see that I'm undercutting her bid price.

[1]-- And by a decent chunk, I mean between 10 and 20%. This is good money, though; glyphs have a low posting fee and high profit margin.
