Perhaps open a clickbank account. Search for a product you may be interested in. Look at the affiliate sales.
It will say "%refd"

If it’s up there over 50% or more then it has affiliates making that much of the total sales. Could be a good indicator of success.

Spend a bit of time at clickbank familiarizing yourself with their program. They are about the best source on the internet today.

If you spend an hour or two a day, you could start building a bit of knowledge. A lot of it is trial and error but the sooner you get your feet wet the better.

Perhaps consider also opening a paypal account for any future ventures. Often you will receive your payments through paypal. You need a credit card for paypal though.

I’m working a new program. Going to give it a couple of months but looks promising.

Whatever you join or do, spend some time with free ads like http://www.classifiedsforfree.com and maybe join sites like twitter and blog there a little about your opportunity or product.

Good Luck.
