The price of milk continues to rise as they begin to reduce the content

UNES supermarket

750 ml package, a format that makes no sense:

2,38 €/l

Next to it was the partially skimmed version, also 750 ml:

2,52 €/l

Furthermore, they also have the courage to write "MUCH MORE" on the 750ml package, advertised in a big way with "NEW FORMAT" as if it were a source of joy for the consumer.

The cheapest milk ever was sold at €1.37/l. Exactly 1 Euro difference.

Does anyone have any idea what’s going on at the milk market?
