I'm not sure what you don't understand. I have done similar offers in the past, but there I knew exactly how they were making money (signing up people to recurring payments on a CC and not really telling them) so I knew what to watch out for. Here, who knows? I told my reasoning to one of the pyramid bricks and he told me that he would look into it. He gets back to me and tells me that they make money from the online shopping they (used to?) have. I told him that I don't think that's enough to cover it all, so I'm not getting involved.
