I can see "Leap from PHP to Django" as a success, as that has a wider audience than the two others. "Django deployment best practices" sounds like a list of items to check or not check (Have I done Y? Check/Uncheck) , so I would personally not buy "X best practices" because I from experience find best practices after some time of playing with X anyway.
