Although I personally celebrate Buy Nothing Day this Friday, I have bowed to the marketing wisdom of the LeanPub publishers and am having a sale on my book this weekend. From 2016 Nov 25 until 2016 Nov 29, the coupon link
will reduce the minimum price of my book from $3.99 to $2.56, approximately a 36% discount! (At other times, it will just offer the usual pricing.)
Once you’ve bought the book, you can download any future versions that I publish through LeanPub (and I expect to have at least one more version before classes start in January).
Note: I’ll be sending coupons for free copies to the students registered for the course some time in December, so they don’t need to spend even the $2.56 of the Black Friday discount.
