I saw a webinar a few years ago with ClickBank University and to tell you the truth I was very impressed. But like you said what I realized was that they are really expensive. Nevertheless, many members have said how ClickBank has made them some really good money. I agree with you, the Wealthy Affiliate University platform has the best online training by far.
WA gives you two sites that uses sublinks. When I say sub-links I mean that they make you go into their servers of (for example as I can’t remember their links off the top of my head as I use so many now) say http://www.whatsiteisit.mysite.wealthyaffiliate.com or something like that where it gets routed somewhere before it goes to your site as you are using their main link and it is rerouted to you through them.
