About.com paid out $800, a few small companies paid $100, but Northrop Grumman took the prize for paying out $9300
Although not explicitly stated, I think there was a minimum requirement of $100 to get a payout from a given company. Checks were issued from each company individually, so you literally had to make $100 from a given company to get that payout.
I think I earned $100 or so but was never paid.
