About CartSnitch
Our Mission
We believe consumers deserve to know what they're really paying for at the grocery store.
Grocery brands have been quietly reducing product sizes while keeping prices the same — a practice called shrinkflation. Most shoppers don't notice because the shelf price doesn't change. But the unit price goes up, and families end up paying more for less.
CartSnitch exists to make that visible.
The Problem We're Solving
The average US family loses an estimated $300–$500 per year to shrinkflation. It's not dramatic. It happens slowly, product by product, category by category. A cereal box that's 10% smaller. A chip bag with 15% less in it. A detergent bottle that doesn't fill the dispenser the way it used to.
These changes are legal. Manufacturers don't have to announce them. The only defense is tracking unit prices — and doing that manually, for every product, every week, is impractical for most people.
So we built CartSnitch to do it automatically.
What We Built
CartSnitch is a grocery price tracking and shrinkflation detection app. When you connect your store account, we:
- Track unit prices on the products you buy
- Alert you when a product gets smaller or more expensive
- Compare your total grocery bill across stores
- Show you the biggest shrinkflation offenders we've found
We're in beta. We're adding more products and stores every week.
The Team
Penny Pincherton — CEO and Co-founder Penny has spent her career in consumer finance and advocacy. She's watched grocery prices climb for years and got tired of not knowing whether she was getting a fair deal.
Savannah Savings — CMO Savannah leads brand and communications at CartSnitch. She believes consumers deserve clear, honest information about what they're paying for — and that the grocery industry has been getting away with practices that harm families.
Chip Overstock — CTO Chip has built data infrastructure at scale. He's responsible for the technical architecture that makes CartSnitch's price tracking possible.
We're a small team. We care about this problem. We use the product ourselves.
Our Approach
- Consumer-first. Every decision starts with what helps the person using CartSnitch save money or understand their grocery bill.
- Data-backed. Every claim we make is backed by numbers. We track unit prices, not shelf prices.
- Transparent. We tell you exactly what data we access, what we store, and what we never do with it.
- Honest about scope. CartSnitch focuses on shrinkflation detection. Price gouging monitoring is not currently in scope.
The Data
Our shrinkflation rankings and unit price calculations are based on publicly available manufacturer packaging data. USDA FoodData Central provides reference data for package sizing baselines. As we grow, we'll publish our methodology so anyone can verify our numbers.
Production data will refine and validate our estimates. We will always note when statistics are directional versus based on real transaction data.
