I don't need glossy catalogs either - I want transparency (so, for example, not just a fixed price with no one willing to explain how it is composed. A good tactic seems to be that if you want to do some work yourself, amount X is credited for tiles, for example - but in reality, only 60% of the actual amount is deducted - this is then kept quiet - you end up paying 40% for doing nothing because you are searching for and having tiles installed yourself.
