The SBAG E201S bag replaces the SBAG E201B. These bags are suitable for a wide range of hoover models. You can check your model by using this link I found. : https://www.sacs-aspirateurs.fr/sacs-electrolux/2657-sacs-s-bag-e201s-e201b-d-origines-electrolux-philips-tornado-volta.html As far as I am concerned, I bought the Electrolux UltraSilencer Zen EUS8ALRGY and both the E201S and E201B bags can be used in this hoover. Hopefully this will help.

Ja passt

According to the supplier, the bags are compatible with the following hoovers: Ultra Silencer, SilentPerformer, PowerForce, Classic Silence, EasyGo, Pure D9, Pure D8, Clean 600, Hygienic 600, Animal 600 from the following manufacturers: AEG, Electrolux, Philips, Tornado, Volta

I ordered the S-Bag E201S. The packaging looks a little different on mine. There are 4x bags included (see 2nd picture below). It does not say whether they are compatible with E201B. Hoover types would be indicated on the package. There are several. It would be good if Galaxus listed them in the description or at least provided a high-resolution photo of the back. What kind of vacuum cleaner do you have?

The pack contains 4 dust bags

As I have a different hoover (Miostar), I cannot answer this question.

Quite simply, the retailers in the stationary trade (supermarkets etc.) naturally buy in extremely large quantities for their branches and thus have better purchasing conditions, whereas with online trade people tend to buy smaller quantities and thus get worse prices.
