You knew that you can sell your old adirondack chair, get a job, buy some orange juice or find a boyfriend on Craigslist. But did you know you can also find a human kidney? Two sisters' ailing father was looking at a 2-6 year waiting list for a donor until they looked to Craigslist to connect dear old dad with a kidney donor. Someone stepped up to the plate and dad got his organ. On the less legal side, another person looking to connect with some cold hard cash tried to sell his own kidney on Craiglist for $75,000. Not so legal.
