When pricing a product, I usually think of the value the customer would get from a product, and also the content you provide.

For example if you have a video course you can charge more because of the value of video. Whereas ebooks are becoming less and less valuable. This is not necessarily true but I tend to think people put a higher price on video online.

It's all about what the customer would get out of it in my opinion, this will also make your customer much more likely to buy from you again.

Hope this helps
