Re: Good idea or bad idea?
I am certainly not the best qualified to answer your question as I am a relative newbie and don't have a massive list, so I still have a significant cost in building my list. A $7 product is not worth it for me as I found my success lies with CB products that have a payout of $30 or more. (Advice from Steve and Tim of Commision BluePrint).
I am also not sure if marketers with big lists would go for the $7 option as you don't want to spam your list. You want to have a reputation where they trust you with offers that you take to them.
My few cents worth
