That warehouse logic makes sense on the trader side too. I believe it means that manual offers always take precedence, and that the manual offer covers up the auto-offer. That means this isn't like an open market where you actually have the option of finding better prices. Well, you could, but that's completely dependent on the lord of the region. In any case, the auto-offer doesn't even come into consideration as a price unless there are no manual offers here. So while buy low sell high works as a very rudimentary sort of mantra, it is applicable for prices among competitors, and not when a price is "hidden" by a single retailer.
