Works great and is great. One of the best things on planet. Finds lots of things one up to can’t get from elsewhere, would be more difficult, one wouldn’t run into them, and so on.
But the delivery options (I am not in Germany) sucks as it will come with a driver that then doesn’t even phone if the outer/inner door is closed but just leaves and then it either is returned or there is some place (regular shop) near one can pick it from, and one has regular troubles with the delivery firm(s) and it takes some imagination to get in communications with some of them, if a success, and then it is with English only until you wait, that I wasn’t willing to do.
But whatever, the delivery is a hit or miss and that’s most what I have seen it to be, so if it is coming, and you know the time, you might better go and wait outside, if you can, so you get your delivery. This is the most frustrating aspect of using Amazon.de.
By the way, there is some book company and the delivery costs are from nothing to next to nothing, if they happen to have your book. Some book repository or so, perhaps.
And all is in English in .de, that’s not the case if using the Spanish site and so, while the USA (good for reviews) and UK ones run into customs, as does China overall.
