There’s also stealth inflation; when a product’s quantity/size is reduced and the price remains the same (or higher) per unit.

General Mills did this last year. They cut the cost of their cereal, modified the box depth (so the box appears the same size on the shelf) and put less cereal in it, but the reduction in price was not as great as the reduction in product, so the cost per unit actually increased…

Has anyone picked up a std. Hershey chocolate bar recently? Those things are almost paper thin!
