Blimey, all my Scourge heavy missiles sell within a day of putting them on the market, perhaps because I undercut the market. I was still careful to make a profit. Considering how many missiles I use on any individual level three mission and how often I am replenishing my supplies I suppose it shouldn't come as a surprise that they all went so quickly in a station with a good level three agent. Even so, it prompts me to start a third run, again an order of magnitude greater than the previous.
I may have made a profit but the margin is small. Never the less, my wallet sees a net gain even having kept back ten percent of the production run for personal use. Had I sold those extra missiles my profit would have been healthy indeed and equipping myself at cost is better than buying marked-up goods from the market. A larger third run should let me realise the profits more readily, although the slim margin on the production runs so far means I have to finance the costs from my own pocket still.
I make the effort to travel several jumps to get cheap minerals so that I can install the next job, which will produce a huge number of missiles. I am keeping track of costs again so it will be interesting to see what profit I can turn and how quickly this next batch sells.
