Inflation is evident when it takes more dollars to buy the same product. But, it is not always readily apparent that it is taking more dollars. Sometimes the manufacturer shrinks the unit to hold the price of each sales unit.
It is still price inflation, but a little harder to spot. It is the smaller candy bar for the "same " price. Same unit price but higher per ounce price.
And it's not just food. Take a look at the current width of a TP roll. Notice how much space is on each edge. Chances are your roll holder was made for a standard width that has gone out of production. It is the same with paper towels. Cut the width and the overall amount of paper is reduced.
My wife has been working on a project that call for small pieces of fabric. She had a little trouble finding a quality product. It seems like the current offering, especially at discount stores is often thin and of poor quality. The cheap stuff doesn't hold up and clogs the sewing machine.
Quality and size are reduced in order to hold the price - for now.
