## The Rankings
### #1 — Yoplait Original (single-serve)
### #1 — Lay's Classic (party size)
**From 15.25 oz at $5.49 → 13 oz at $5.99**
**Unit price increase: +28.0%**
The most recognizable chip brand in America is also one of the most aggressive shrinkflation examples. Lay's cut 2.25 oz from the party-size bag while adding $0.50 to the sticker price. At 28.0% more per ounce, this is one of the worst double-hit examples in the dataset — and a brand so ubiquitous that most shoppers never think to check the weight.

### #2 — Yoplait Original (single-serve)
**From 6 oz at $0.79 → 5.3 oz at $0.89**
**Unit price increase: +30.5%**
**Unit price increase: +27.5%**
Yogurt has been one of the most systematically shrunk categories in the store. Yoplait pulled the double move: shrink AND raise the sticker price. A 0.7 oz size reduction plus a $0.10 price increase works out to $0.044/oz more — a 30.5% effective increase on a product most consumers buy without checking the weight.

**Unit price increase: +27.0%**
General Mills combined a 2.9 oz weight cut with a $0.30 sticker price increase. On a breakfast cereal that families buy in quantity, the effective per-ounce increase is nearly a quarter higher than it was four years ago.

**Unit price increase: +24.3%**
**Unit price increase: +23.6%**
Party-size chip bags have been systematically reduced without reducing the bag dimensions. Ruffles cut 2.25 oz while raising the sticker price $0.30. The result is a bag that looks identical on the shelf but delivers significantly less product per dollar.

### #4 — Lay's Classic (party size)
**From 15.25 oz at $5.49 → 13 oz at $5.99**
**Unit price increase: +27.0%**
### #5 — Cheerios (standard box)
**From 18 oz at $5.04 → 15.4 oz at $5.24**
**Unit price increase: +21.5%**
The most recognizable chip brand in America is also one of the most aggressive shrinkflation examples. Lay's cut the same 2.25 oz from the party-size bag as Ruffles — both are Frito-Lay products — while adding $0.50 to the sticker price. At nearly 27% more per ounce, this is one of the worst double-hit examples in the dataset.
Cheerios is the most bought cereal in America. The 2.6 oz reduction across hundreds of millions of boxes adds up. At a 21.5% per-ounce increase, the brand maintained its price perception while meaningfully reducing what consumers get.

### #5 — Lucky Charms
### #6 — Lucky Charms
**From 19.3 oz at $5.01 → 16 oz at $4.96**
**Unit price increase: +20.6%**
**Unit price increase: +19.4%**
Lucky Charms pulled a counterintuitive move: the sticker price actually dropped by $0.05 while the box lost 3.3 oz — the largest absolute weight reduction in this ranking. The result looks like a deal at the register but works out to $0.052 more per ounce. General Mills gets full marks for execution on this one.

**From 5.3 oz at $1.59 → 5.0 oz at $1.69**
**Unit price increase: +12.5%**
**Unit price increase: +12.7%**
Greek yogurt in general has seen consistent shrinkage. Oikos Triple Zero combined a 0.3 oz weight cut with a $0.10 price increase — modest individually, but on a product that loyal buyers purchase 4-8 times per month, the compounding effect on a household's annual yogurt spend is meaningful.
