Question about Playmobil Big princess castle

How can it be that this lock cost 122 just a few weeks ago, then 130 and now 176, mind you, without offers such as the discount campaign that recently took place. I have no understanding whatsoever and not only you but the whole of Switzerland is ruining its own business, which is exactly why so many people go to neighbouring countries. I am always willing to pay a Swiss surcharge, but this is a rip-off and no one will put up with it.
