Yes, I totally agree! The price point on this is very high!!
Though, I have seen copies on amazon for less than half the list price. Quite by serendipity, I was able to snag one for under $30… But I don’t know how often this availability occurs.
Also, I just quickly checked on amazon and it looks like another option, while not optimal, is to rent. The first month is $16, and then an additional $4/mo thereafter. The downside of course is not having the book as a reference once the rental period is over. But perhaps this is not so crucial as the information in the book is so foundational one would not need to refer back after the concepts were learned(?).
I will certainly follow through on this. I have some definite opinions — largely positive, along with a couple of user experience suggestions — that I’d like to share…
