Help me understand?

[alisa1975]

I notice that most of the offers are to sign up for something or order some product or service.  I am a little confused on how you can make money if you have to buy a bunch of crap.  I do no mind doing surveys, answering questions, or even watching a video but i cant afford to buy.  Are there something I am overlooking or  was I mistaken about FC.  Please explain?
