Question about Jura Claris Smart

Yes, that's an exciting comment. Can't necessarily be justified with inflation, supply chains, lack of skilled workers and trallala. The prices at Galaxus and Digitec are quite volatile. If you order a product and then look at it again in the shop, the price may well have changed by 10%. Upwards, of course.
The cheapest supplier is currently about +16% higher than your price, which also points to an unpleasant development in Switzerland.
The good news, however, is that the money is not lost, it just belongs to someone else.

...and the ones from Amazon (3 for €33.40) are the new Smart+ model.

Fortunately, the old prices still apply on Amazon :-)
