I have a friend who has created a great course on betting. He wants to add it to clickbank. He is selling the course as 2 options. Option 1 will get the ebook Option 2 will have ebook + live video course of him doing n teaching a profitable trading method. Now does clickbank allow 2 different pricing options on sale page.
Yes, this is very common, you could either list 2 options on the main sales page, or have a "1 click upsell" in between the sales page and the clickbank order page asking them if they want to upgrade to the full video package. All you have to do is create a second product on the same clickbank account and this is easy to do, but if you look at the official clickbank documentation it will explain this and what to do.
