I wonder how these lesser amounts work out in grams and liters.
I will tell him you said so. But he’ll just complain that everyone is against him. He’s kinda pitiful.
Yes I believe I recall your other post, and me like others have not noticed any air in toothpaste tubes. Since that former post I have not noticed any air also.
Well like I said, I apologize you had to read it again.
As to the original OP and changing sizes, it could be presented to us by clever marketers that the food industry is trying to help all of us overweight Americans with portion size by making everything smaller, but really, they know you will just by 2 to make it come out even. So either way they come out ahead, and the consumer doesn’t.
Oh, yeah, they sometimes do that, too. 100-Calorie snack packs, anyone?
Canned pumpkin is no longer a pound, so I had to adjust my pie recipe accordingly. Mayo jars are no longer a quart, they’re 30 oz.
I think the only things unchanged are a pound of butter, a gallon of milk, and a dozen eggs.
Wow you’re right. I just checked a couple of Chobanis in the fridge and they are indeed 5.3 oz. I think the store brand yogurts are still 6, but I don’t have any in the fridge at the moment to verify.
Good news though - the sour cream is still 8 oz! (Unless it used to be 10. 
)
This shenanigan has been going on forever: the company knows that people will complain or rethink their purchase if they raise prices. So, rather than charging more, they sell less for the same price.
Consumerist used to call it the “grocery shrink ray”. You can still read old articles about it here. One of the most egregious examples: McCormick’s ground black pepper. They reduced the amount of pepper in a tin, in one case from 8 ounces to 6 ounces, but kept the size of the tin the same.
Pasta sauce at the warehouse clubs is still 32 ounces (as of the last time I looked). We reuse the Mason jars they come in for canning things like chili and chicken stock. Recently they’ve gone to a nonstandard lid size for some jar sizes, which throws a wrench in our frugality.
