I agree that one should always add this general warning whenever they are mentioned. I can’t see how they benefit from my visit if i am using ublock origin and remove all the relevant cookies and parts of the url that would give them a commission.

You can use them and then delete the parameters and cookies, stuff like ?p=65536&utm_source=PSM&utm_medium=idealo_de&em_src=pricecomp&em_cmp=idealo

Ah funny, that was exactly my suggestion in another comment :) too late

Here it is for around the same price 23,28 € + 4€ shipping in Germany

Despite that, you can sometimes find the web shop of the vendor where they sell it cheaper or for the same price as on amazon.
