In Germany it is. In fact, you could not find it at any supermarket for months. I even bought an air fryer in the meantime to sort of compensate. It has gotten better again recently though

Wow. €5 or thereabouts nets you three litres here and I think restrictions on purchases have been lifted recently. Some supermarkets limited you to two or three bottles per purchase for a while. Considering that we all get our sunflower oil from Ukraine, not sure why it's so much more expensive in Germany. Maybe we had bigger stockpiles here. I dunno.
