OK Hougee, I am one of your referers so now I need 5 people to sign up too
according to Wired, it's legit. check the articles on http://www.wired.com/news/mac/0,2125,64614,00.html
Just go to the site, pick your iPod, refer 5 friends or send out the url it gives you, then complete one of the sponsor offers. I picked the inkjet one and got the cartridges cheaper than usual (I used to get em with Carrot Ink) and they also put in free blank CDs and free mag subscription to Forbes (well I chose that one because I didnt really want Blender or Bride or Golf).
You might sign up for some junk mail, but that doesnt tend to bug me too much. what bugs me is spam but I'm sure you all have those clever emails for offers like this so that spam gets consolidated there.
