You can't use that to detect shrinkflation unless you remember the old price per unit, right?

Some NZ supermarkets have that kind of labelling, but not always for every product.

My regular (soon to be former) cereal has gone from 700g to 620g to 535g in about 3 months, all for the same price. The box has the same width and height, but the depth has been shrinking.

I'm creating a browser extension to display unit pricing on some NZ supermarket sites that don't have it.
