Question about Yeelight Smart LED Filament Lamp (Bulb Shape)

@Galaxus, is the sudden price bump from 20.90 CHF to 52 CHF intentional? I guess this is due to a supply shortage and increased demand because the general shortage attracts people from other stores, but it feels quite dodgy and I doubt anybody in their right mind would actually pay that price. Even leading brands like Philips have similar offerings for less than half of the current price.
