It depends. Lots of places that I have been to usually have lots of hidden extras and you end up paying more than the quoted price, or the quoted price is only if you finish in the bare minimums without going over (which almost never happens).
Some places will quote you a price, but it doesn't include exam fees, testing fees, security badge fee (if applicable), membership fee or a nonmembership supplemental fee, insurance, fuel surcharge to cover increasing fuel costs, etc. Like I said, I all depends on the school, and it seems worse at some schools than others.
The only place where I have been and I paid exactly what I was quoted was Aerodynamics Malaga, and their price includes all charts, testing fees, and paper manuals. Also, I think you will find that there are usually no extra hidden fees at many MCC courses.
I also found that BCFT was pretty good at charging a fair price without hidden fees, but skill test and license issue fees are on your own and not included in their quoted price.
I'm under the impression that many flying schools have such little margin that they can't afford to charge less.
