They have a lot of things (excluding books) but they are only interesting in switzerland: Galaxus.ch (their site is available in english, german, italian and french). They have the best speed and filters i have tried. And the ui is relatively compact compare to other online retailers i have access to. Reichlt in Germany has good filters but they are very slow where i am accessing them from.

Unfortunately every retailer are also starting to be a platform for other shops as well, inflating their numbers and polluting their search results.

Amazon really has terrible filters and search.
