I’ve done this before with tuna cans and probably the coffee–did you know that once upon a time they put a full pound of coffee in that same size container that now holds anyplace from 11.5 to 13 ounces?–but here’s a brand new one.
Dial soap. See how it’s carved out at the top? Yes, it’s a new design, but it also has shaved .25 oz. off each bar. You used to get 4.25 oz. in a bar, now the bars are 4.0 oz. but the price has remained the same, or maybe gone up.
I fully understand that prices go up. Over the past 40 years I’ve seen things rise to ten times their cost. Houses ($40k to $400k), cars ($2k to $20k), a quart of milk $0.25 to $2.50), etc. A pound of coffee used to be $1.00. I don’t mind rising prices, though I wish salaries had gone up 1000% as well (minimum wage was $1.25, now $7.50). I understand that times change and costs and resulting prices adjust.
I just hate when marketing thinks itself clever and insults us with carving off .25 oz. of soap or packaging a half-full box of crackers.
