You are funding one of the oldest scams in the book. This has been done for ages in various forms with various products as door-to-door and direct phone marketing. Currently where I live they are doing it with socks and underwear. You are lured in with "too good to be true" type deal, and hustled to sign into a continuous contract that is hard to get out of. I'm not sure about the current legal status, but I wouldn't be surprised if this business practice wasn't outlawed around here soon since it's been in the news quite a regularly.
