product shrinkage." Rather than raise prices, manufacturers decrease the size of their product, sometimes overtly, and sometimes in as subtle a fashion as possible. The dimple on the bottom of a bottle may get deeper, the package may become tapered, there are fewer items in the non-transparent bag.
The photo above shows an example our family recently encountered while replacing a paper product. The cardboard roll from the previous item (same brand) fits easily inside the roll of the new product.
I hope they don't increase the size of the hole in Krispy Kreme doughnuts.
