Did you ever have second thoughts about doing a launch?

What I am about to say is completely imaginary. Consider the following situation:

If you were creating an info product around a system that has helped you scale your business rapidly without much work and it works like a charm every day. You open up your analytics with 100% sureity that your audience has growth atleast 2 fold compared to last week.

Towards the end of completing this eBook, you know that you have to price it such that people who can use this can buy it. Since its not like some rehash and it infact contains solid information, you price it under $30(ONE TIME FEE) so that people actually can buy it.

You are about to launch the product, you have got everything setup. You make payment for the sales page to be ready. You realise that you are selling a system that if sold as a service can get you around $40 to $60 per month from a single client. You could easily get atleast 5 to 10 clients per month. This means if at the rate of 5 clients per month at the rate of $40 per client, this exact system can fetch you $2400 per month after a year.

What would you do? Markup the price?(Remember, it is an eBook). Will you make it a video training course that can be sold for like around $397 or maybe $497? Abviously you have to limit the sales to prevent too much competition.
