Yeah, it was about a thousand bucks the last time I checked and probably more now that he's passed. Why I ultimately didn't feel too bad about not reading it was because from what I understand, its contents are ostensibly mostly covered in Nature of Order. Same goes for Linz Café. I am, however, glad I read The Mary Rose Museum because it has a contract in it (excerpted in Nature of Order) that inspired me to write my own service contract "from scratch" (for some value of the term).
As for the software industry, it really latched on to patterns because (and Alexander himself nails it) they offer both a format and a formula for exchanging ideas that are either too ephemeral to write into a library, or otherwise transcend particular languages/frameworks. A lot of the really important insights though appear to have been lost in the process. (I have the Gang of Four book and a Fowler book, and have found neither to be especially useful.)
