As the picture shows, most (all??) grocery stores will show the price per ounce on the item’s price tag.
It’s usually on sales tags too.
I was FAR too old before I realized this and it’s made price comparisons in-store much easier.
Note: Not my photo. Just generic photo from google.
One annoyance is when the unit is different for items of the same type.
Produce? Priced per pound (usually). BUT the comparison price is per kg for some reason? Except not always?
Liquid? Per 100ml, except for the one specific thing you want to compare, which is measured per volume of a size 10 sneaker.
Dry goods? Per 100g or kg (or rarely, pounds) with no rhyme or reason as to which they choose.
Toilet paper? Compare “sheet”, which will require a terminal degree in advanced mathematics to calculate (one roll of SUPER PLUSH is equal to 7.2 rolls of MEGA PLUSH, which is 4.875 of double, which is anything except twice as many as).
In Canada, we actually have a big colourful wheel that Chrystia Freeland spins to decide what unit we use when measuring a specific thing.
Experiencing this all the time in the US. Want to buy extra virgin olive oil? One is priced in “per floz” another in “per quart” and a third in “per pound”. All three contain same EVOO in the same size range (500mL-1000mL) on the same shelf. How many ounces are in a quart? Is a fluid ounce the same as a dry ounce? Fuck you! Hope you are skilled at multiplying by 16 in your head. I swear the grocery stores do this on purpose to protest the fair pricing law that forces them to display the unit price. If it were left up to random chance alone, the units would match at least some of the time. EVOO is the reason I hate the imperial measures system.
In Europe it’s required by law for most items. And it’s the only price I look at when I buy stuff.
