Well, if you chose that option, and don't make the cut, Indiegogo charges you 9%. If you hit the goal, they only charge you 4%. If they don't get the $32M, that would mean over a million dollars for Indiegogo.
Personally, I don't like indiegogo purely because they charge you immediately. They refund you if it doesn't make it, but anyone who knows if you do a currency conversion, that's a good way to give the banks free money (around 5% or more, depending on how the currency fluctuates). Kickstarter only charges when it goes through.
