Not affiliated, but for Germany I'd check https://gh.de ... For technical products you can filter for mostly any relevant detail... At least most German shops are there, and only a few not.

I am always curious why there doesn't seem to be something similar everywhere?

Thanks for the input!

As I mentioned to other users, Amazon's pricing seems to be quite dynamic. This data is just 4-5 hours old, but it already seems quite stale.

Note taken that it should be updated more frequently!
