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.
Clickbank University is a good product that's worth the monthly membership cost of $47/month. I think that for someone looking to create and promote their own digital info product through Clickbank, this is probably going to be your best investment. If you are an “expert” in something and want to make money off of your knowledge, now's the time to start!
