I use auctioneer all the time, and when posting items I have it set to undercut my competitors by 1%.
However, if there is no competition for a particular item, it simply sets the default to the market price.
Is there an option in Auctioneer to set it so if there is no competition, raise the default markup price by 100% or by 50g (for example)?
Basically, if there is no competition on an item, I might as well put it on the AH for a high price, rather than market price.
