Is it allowed to post complete offers in anonymized form?

If you want to know if the prices are usual, you can also get several offers made, that is then the easiest way to compare.

Principle of tendering. Moreover, these offers are then also easier to compare.

In the photovoltaic example, I find that okay, the form is abstracted, everything is very interchangeable, a simple product, and exact plans are missing there.

With the house, it may be different. The larger the company and the more commission-driven the marketing and the more standardized the house, the fewer qualms I would have. However, I would never think of posting offers from our small general contractor somewhere.

Prices are listed in the providers' catalogs, at least in our case. This gives a very quick first overview.

I don't understand the fairness objection – but also not what the OP is really about: that someone posted ten pages of construction service description here would be no novelty. Such "look at my offer" threads keep popping up now and then. And the responses are basically always the same, like "the sly ones 'forgot' your construction electricity" and the like, or in extreme cases "turnkey here only means the front door."

Too bad, that happens often.

Well, then just explain it. I haven't seen secret offers with only-for-you special prices that must stay between us - only on plans the note that passing on or using it outside of the order is prohibited.
