If only smart glass is as popular as mobile phones. When Google introduced their smart glass, I dreamt of a day when a price history overlay is displayed when looking at a barcode, like how Keepa is doing for Amazon.
I also like German price display which has effective price, as in Eur per liter for drinks, making it dead simple to compare products. A smart glass will make it available everywhere.
Back to Carrefour, I really like that they are pushing pro consumer actions. However, we all know too well that they won’t do the same when it’s their products which are shrinking. Still better than no action though.
Afaik the base price display is requiered by EU law, atleast Czechia got them too on my last vacation.
it’s so good too, you can cut through all the bullshit and simply check if per kg/liter It’s cheaper or not.
even though for a lot of stuff it’s simple math. 100g you just 10x, 250 you 4 x the price, 200g you 5x.
but there are lots of stuff that’s packaged in weird amounts. 230g yogurt, 180g tofu.
you don’t want to break out the calculator for shopping.
Your comment made me realized that displaying the price per kg is not a standard everywhere.
This is the only price I’m looking at when doing groceries.
Same for me, I got so used to it.
The only annoyance is when (mostly brand) stuff is purposefully displayed in a different unit (e.g. washing powder in washing loads instead of kg). But imho that kind of obfuscation speaks for itself…
