No, the client being to lazy to make uninformed decisions him- or herself is the mess here. Most countries require a price per liter/per kilo anyway, so you always can compare.

And if you can’t, more regulation won’t make that happen, either, see the failed "Nutri Score".

See the greatly successful nutrition info block on everything in the US.

no-one commits the price for litre/kg to memory

This is a super privileged opinion and wildly out of touch with the less fortunate classes of society.

Also, if you don’t commit to price comparison, how can "shrinkflation" be a problem? If you can buy whatever groceries you want anyway, just buy the ones that make you feel comfortable regarding their price policy...?

I roughly remember the unit price

I am not going to remember that last week it was 490g if they silently reduce it to 480g

this is why they do it... because it works

> Also, if you don’t commit to price comparison

I do price comparison at the point of purchase

but I don't remember the price/ml week to week

> This is a super privileged opinion and wildly out of touch with the less fortunate classes of society.

That's clear bait. What you're advocating for is a mental tax on the "less fortunate class" as you put it.

Make price transparency legally required and see how the game changes.

This, the concern trolling of corporate apologia is becoming absurd.

“Don’t patronize poor people, of course they are smart enough to remember the ever shifting prices and unit sizes of every product in the marketplace to calculate the real price changes in the goods they are buying.

If you shop often enough, you do start to remember it. I buy a lot of groceries every week and would absolutely notice if things got smaller or the unit price got larger.

they never reduce it enough for you to notice

(unless you're explicitly checking the weight each time)

Then the unit price changes.

which changes all the time with regular price fluctations/discounts/etc

I have noticed e.g. with toilet roll when they decrease the weight they bundle it with a temporary discount so that the unit price remains the same (or even decreases for a bit)

then once the discount ends you've forgotten that they decreased the weight

it's a random walk, with the shrinkflation causing it to go upwards over time

it's the same trick e.g. Google does with Google Workspace, when they want to increase the price they:

  - increase regular price, but introduce a new permanent "12 month plan" with the previous price
  - six months down the line the 12 month plan is discontinued

then they repeat next time they want to increase the price

In this country, equivalent products on the shelf alternate between listing a price per oz, and a price per lb, to make it more difficult to compare the two.
