Well DAZ's model is an electronic download content company, who is always having a sale. Most of that content is made by PA's. So they would have to be willing or able to adjust to change that. I don't see any indicators that that will be changing anytime soon. An option of a hard copy would have been nice.
I personally have just been annoyed that affordable e-readers haven't been available. Even now they aren't. There's one company that you can get one from w/ a book subscription. I like reading and being able to sit down and read where I want, but paper books are difficult  to update and I find they take up waay too much space and are heavy to move. The bookshelves I have would be much better served being used for something else. Storing books, moving them and getting rid of them just gets old. So much easier to find things electronically than via paper also. The maintenance is ridiculous.

No need to think outside the box....
