Effective price-per-unit increase
At the tracked shelf price of $5.99, that's $0.3928 per oz before, versus $0.4608 per oz after — a 17.3% jump in cost per unit even though the sticker price never moved. This assumes the price held constant across the resize, which is the defining trait of shrinkflation.
