Okay, they don't, but in this case at least, it has proven to be true.
A spokesman for PepsiCo admitted that Classic and regular flavored Lay's Chips come in 10-ounce bags and flavored Lay's come in 9.5-ounce bags. At those sizes, all bags have a suggested price of $4.29.
And it is those flavored Chips that the corporate behemoth can use to help tackle the fall in profits of snack foods, and their own companies tiny fall in profits.
