It has always been like this in my country. We have multiples of 330ml or 500ml

EDIT: I just noticed now and yeah this is false advertising

I thought the same, but they still make the 20 Oz bottles. Looks like the vending machine company is either cheating people or forgot to update the placards - https://www.target.com/p/pepsi-cola-soda-20-fl-oz-bottle/-/A-12979694

Damn, that is why I can’t get my hand into the pringles tube. It is smaller in diameter.

Shrinkflation happened to this guy, also.
