Hi, Stanley.
Just my opinion, but the main thing you need to consider is to already have good sales on a regular basis.
If you have say, $500 or more each month, that might be a reason to go exclusive on a site,
but in all honesty, it is otherwise just a nice dream.
Not saying to give up on your dreams, but keep things in perspective and you will do better.
