In another ode to self publishing, DIY author J.A. Konrath posted a blog this week where he revealed that he earned $100,000 grand on Amazon in the last three weeks.

Here is more from his post: “This is just for my self-pubbed Kindle titles. It doesn’t include Shaken and Stirred, which were published by Amazon’s imprints. It doesn’t include any of my legacy sales, print or ebook. It doesn’t include audiobook sales. It doesn’t include sales from other platforms.” He shared his sales report of sales from this year on his blog and we’ve included the infographic above.

Despite the fact that the holiday retail season is over, Konrath is still doing well this month. In fact, the author says he has is averaging “well over $3500 a day” for January.
