Often I see CPA offers like this: "Get a Free Ipod NOW!" and so many more. I just don't understand what the advertiser has in mind by giving high priced stuff like that for free. I mean after they get the emails, do the advertisers promote other stuff to the consumer to fill out before they get the Ipod? Generally speaking, what do the consumers have to really do to get their "free" stuff? (I just used the Ipod offer as an example. Feel free to talk about how other "free" offers work). Thanks to anyone that can help me out on this.
