The prices of my 3 data journalism ebooks — Data Journalism Heist, Finding Stories in Spreadsheets and Scraping for Journalists — have been cut to $5 on Leanpub in the lead up to Christmas. And if you want to get all 3, you can also get the data journalism books bundle on Leanpub for more than half price over the same period, at $13. Get them while it lasts!
