Yeah, but it's more like government request rather than selling at any time to unknown forces (well I knew where my muton corpses were going

You'll get occasional requests from specific governments for specific items, but the Grey Market is an any-time, anonymous sell. The requests are usually for more than the Grey Market, so again there's the trade-offs - do I sell my alien goo for cash now, or save it in case a Canadian corporation asks their government to find something to spice up their poutine?
