Questions about Bambu Lab P1S

What is the difference between the two products which have exactly the same name "Bambu Lab P1S" but a price difference of 10.-? (I don't mean the combo product, that would be the third P1S variant)

The Bambu Lab EU store has them in stock, and here I'm supposed to wait until May?

Do I see correctly that there is no AMS included here? If so, it's really overpriced here. Printer + AMS are even cheaper from the manufacturer than just the printer here.

Is this the "P1S" or the "P1S Combo" with AMS? According to the description and pictures it is the "P1S" without AMS, but the price of CHF 959 is so much higher than other suppliers (from Switzerland and Germany) that it should actually be with AMS?

The picture and the description are correct. The package with AMS is called P1S Combo. But you can also buy the P1S without AMS from Bambulab itself.

Just to be clear: This is the P1S with the AMS, right? Since P1P would be the one without the AMS included. The picture tell me that the AMS is not included.
