The biggest problem to get my first check from clickbank was the task to meet the customer distribution requirement. I earned over $100,- with some sales but they all got payed with paypal. I'am a Newbie at Affilate marketing, so my sales come in slowley, but hey, I make about 2 sales a week. Anyway, this guide helped me allot to meet the customer distribution requirement. It's free and only a 16 pages PDF, so it wont take you long to read. The guide shows you how to get small sales that earn little so the chances are higher that people pay with diffrent payment methods. The risk that your account gets dormant are also relativly low with this method, because you get small but steady sales.
