Surprisingly you get a lot more abroad than in the US, according to the Google. 3.5 k for a kidney (which frankly sounds crazy cheap, used car pricing with similar life expectancy, but for something you can't get off a lot), apparently more like 10k if you go to eg Mexico, but more hassle, risk, and overhead.

Just another day , another wiki dive , that probably gets me added to (another?) government watch list lol
