Emperor Krulos is retiring and selling his old arsenal at a bargain, I see. Sturdy ship, only crashlanded once

When your villain organization is running low on resources after the whole phazon debacle, you've got to make some of your weapon acquisitions by purchasing rather than manufacturing them yourselves or just stealing, your underlings are chosen by their ability to follow orders, not to question what they're told, your boss is an artificial intelligence who, though in many ways brilliant, was originally created for archiving purposes and doesn't know the first thing about haggling, and your boyfriend is out fetching some metroids and won't be back for a few days (he said not to worry, what are the chances he'd randomly run into Samus or something, right?), who's going to deal with making sure your space shopping cart isn't full of "great" deals like "lightly used bombs"? Not the ghost or the fish.
