Real down-sizing

Instead of responding to inflation with price rises , the food industry is reducing sizes and weights. The food industry know that people are much more conscious of price than they are of package size or net weight of contents. And the manufacturers hide their handiwork by indenting the bottom of containers (a favorite trick among peanut butter processors) or whipping ice cream so that you pay for air instead of ingredients or re-designing the packaging with cheaper alternatives .

In a new advertising campaign Farm was labeling its German Dark Wheat bread "New Size, New Price." The old loaf weighed 24 ounces and cost $2.66 per pound; the new was 18 ounces and $2.92. Less for More!
