This is why I have asked twice to see the logs from fetch. We can at least see what sources are being used and if there are errors. Though, maybe you have sorted this out.

But, if price, reading age and "weight" (I don't know what you mean by this) are important, than you are probably wasting your time. None of the metadata source plugins will get these. And in fact, very few of them have them on the site the the metadata is fetched from. The source site would need to be a shop to have the price and I'm not sure if I have seen anywhere that has reading age. There is also a technical issue. The metadata source plugins can only updates the core metadata. Price and reading age are not part of this. Which means that even if they are available on the site, it isn't easy to fetch them into the library. You can store these in calibre using a custom column, but, you will have to populate them by some other means.

@davidfor - on a freshly installed calibre portable with default settings (including MD sources), I can't get a MD download for the following book,

Spoiler:
