It is Thanksgiving week in the US, which means that all real-world and online retailers are luring buyers with all kinds of crazy sales.
Here at Scripting OS X, I keep the book prices low all year round. My latest book “Moving to zsh” is US$9.99 all the time.
I also just permanently lowered the price on “macOS Installation.”
Nevertheless, starting today and up to Dec 3, I will also put “Packaging for Apple Administrators” and “Property Lists, Preferences, and Profiles for Apple Administrators” on sale!
And not just for US readers, but on all regions where the books are available in the Apple Books store!
