It was a redundant skill, so we had no problem cutting it. As others have pointed out, it was a) already covered by other skills, and b) a bit too magical in implementation. Most times Streetwise covered things, but if the players were outright salvaging I asked them for a tech skill, and if they were dealing with a bureaucracy then Protocol covered it. Sprinkle with negotiation, appraisal, and contacts as necessary for flavour. I also rewarded people who had black market or quartermaster contact with roll bonuses if they were in the right region.
