Why, pray tell, is a Pre-Calculus book $235?
http://www.amazon.com/gp/product/0840069421
Our students (and their parents) are being robbed at a monumental rate. What can possibly justify this kind of a price for a subject that has seen no change for decades. Why can't my kid use my pre-calculus book from 30 years ago? Have the definitions of slopes and limits changed during this time?
Even the used versions are highway robbery. A Calculus book ought to not cost more than $20 (or be free).

All I keep reading is Americans blaming the evil publishers for their greed and profiteering. However that is a publisher's job. It is in their DNA, they're a profit making business, they aren't meant to do the right thing.
Instead the people who should be "blamed" are the schools/departments/academics. These are the people who assign a $235 book, these are the people who's job it is to spread knowledge and educate people. They're the "gatekeepers" and they're asleep on the job, or worse in cahoots with the publishers (because publishers give them a way to keep tuition lower, by doing the grading on your teacher's behalf via one-time-use codes, instead of the school/department needing to hire more graders or develop systems).
A lot of schools/departments/academics have solved this issue, they're developed free or "open source" books and other material. But many either don't care or are benefiting from the relationship with the publishers.
If you wish the situation to change then complain in the right direction: To the educators, school, department, or similar. Publishers are just going to laugh at your complaining with good reason.
PS - In many other countries this issue doesn't exist, not because $200+ books don't exist (they do), but because educators haven't lost sight of their role as gatekeepers to knowledge and education. Many of my own teachers wrote all of the course's material in-house and then made it available for free, they re-used the same material every year for the same course. It was like $5 to print it all out (just in photocopier/binding costs), but digital so just bring an iPad if you wish...
I am an academic. Unfortunately this answer is correct.
Still more unfortunately, one reason that this persists is that it's in no one's self interest to create an alternative. What I'd really like to see is momentum build for high-quality, wiki-style textbooks where lots of teachers from lots of different institutions collaborate. Unfortunately, this isn't happening much.

Not terrible, but not as good as commercial textbooks. (Please let me know if you are aware of anything better.)
I studied precalculus in India. There, the textbooks are all made available online, viewable by anyone. Give it a try!

Specifically, for grade 11 math: http://www.ncert.nic.in/ncerts/textbook/textbook.htm?kemh1=1...
The idealistic suggestion would be that if you know the material well enough, you will be capable of solving these kinds of problems. In fact, the professor will teach from the book in his class right? At least take notes about the kind of stuff that he covers and study that. Yes, people with the books who have practice solving the same problem will find it easier, but you won't find it impossible either. And the test itself will be more honest, don't you think? :)
That's what I did in college, but I understand that not everyone will want to do the same.
I'm writing a free mathematical book, and pretty much want to continue it in the future (tackle other topics). We need an open book movement. Alan B. Downey has been doing it, all of his books are free. Khan, of course, is doing it, but in video format (so far).
I'm not a fan of 'shame the publishers' approach. They are trying to make a living, and turning out new books does that. Plus, they are also responding to government - we have some new initiative, tons of new material has to be developed so students can 'pass the test', and if the textbook is only going to be around for 5 years they legitimately have to charge a lot to break even.
I think online, free books with cheap printed versions is going to (or should) change all of this. The whole idea of 'editions' is outdated. If something needs to be changed, make the change, and push it to the cloud. If you made some typo, push the change tomorrow, don't spend 6 months proofing galleries. The economics of dead trees doesn't work when I can get an email from a confused reader and push a better written explanation a day later.
It's already happening [1]. Let's make it happen faster. It's more important than the next jSomething interface, or 'like Waze but for dogs' app.

And, I'm not sure where common curriculum comes into this, or if it does.
The reason that universities "upgrade" to new versions is that publishers refuse to continue printing the old ones.
Indeed, my university (the University of South Carolina) had this stunt pulled on us by Cengage (the publisher of Stewart's Calculus), and we are refusing to play ball. So we've decided that we are absolutely going to use something other than Stewart next year. Unfortunately, the best alternatives also all cost around $200+.
The professor, or one of his friends, writes a textbook.
That is now the required textbook for the class, and the professor gets a cut of the profits.
Some textbooks are so good or popular that they are used by everyone, even if they aren't the author's friend. (Examples in CS: CLR, Dragon Book.)
The students must get the official textbook for the class, because all the homework exercises are assigned from that book.
It would be nice to see some effort for open source textbooks, but I don't see them being adopted in K-12 or colleges.
And problem sets need to be updated or they will feel dated very quickly. Especially if you are supposed to be using technology to help solve the problem.
Dover prints classic mathematical texts which are wonderful. There is nothing wrong with them. I've learned so much from them.
But, you know, I could be wrong (I'm serious, not trolling). I'm white, was lower middle class but had a great set of schools/teachers, and maybe the books are terrible for ESL students (for example), and I just haven't run into the problem because of my background.
With that said, I don't think the linked book is an example of new pedagogy. I'm eager to stand corrected.
Changing teaching methods?
Because people are buying them at that price?
