Yes, i wonder if they offer to "buy a kidney" from an individual for say 60K-70K the costs might be gobbled up in follow-up care or hidden costs too.
I would never make a live donation of one of my organs for someone I don't know. My grandfather ultimately needed both his kidneys, because he got a tumor in on kidney that was discovered on his last foreign vacation when he was 72. He ended up living almost another 11 years with his remaing kidney.
