I'm new to affiliate marketing, and have no experience with CB. I was just looking around at some of the pages for CB products, and one of the pages has an opt-in form right at the top. The cynic in me can't help but wonder if the seller is trying to sell product through e-mail and screw affiliates out of commission. This is a pretty popular product with decent gravity though. Should I steer clear of products whose sellers use opt-ins?
