That is a good price. I have a significantly more expensive offer and the profiles look pretty much the same as yours (if not even the same ones). Was installation included? Can you tell me what to google to find out who your provider is? Alternatively, feel free to send me a PM. Unfortunately, I don’t have enough posts to write to you.
Anyone living in NRW, especially near the Dutch border, should definitely take a look at the Netherlands or request offers from providers there.
