Congratulations on the success!

From your post: "20% of the revenue came from $499 company licences. This is good, but it’s only about 2% of the number of purchases", I did a simple math:

20% * $10,000 / $499 = 4, 4 / 2% = 200.

May I ask over how long a period did the sale pass $10,000? What is your average daily # of sales?

Also, pricing strategy is always a fascinating topic, how did you come up with a price of $47? Thanks!

Your maths are correct. I started selling the book in January 2012. However, I think I could have achieved this number of sales much faster if I dedicated more time to marketing (e.g. if I published the same number of posts in half the time).

Pricing is something I learned about from 30x500 as well. I looked at the anchors my potential buyers might have (C++ books are often around $50).

I looked at what else they buy and at what price (courses, software etc.).

I also considered the value of the book to them. E.g. for a C++ contractor, the book would pay off very quickly because of the time savings it provides.
