| Why We Built CartSnitch | why-we-built-cartsnitch | draft | 1.0 | 2026-03-20 | The story behind CartSnitch — why grocery price tracking matters, what shrinkflation is doing to household budgets, and why we think consumers deserve better tools. |

Why We Built CartSnitch
A few years ago, one of our founders was doing the weekly grocery run at Kroger. She had been buying the same box of pasta for years — same brand, same shelf, roughly the same price. But something felt off. The box looked identical. The price was actually down a little. But the pasta was gone faster than usual.
She checked. The box had gone from 16 oz to 13.25 oz. The price had dropped from $1.89 to $1.79. The price per ounce had gone up 15%.
She had been buying less and paying more, and she had no idea.
That is shrinkflation. And it turns out it is everywhere.
The Invisible Price Increase
Shrinkflation is what happens when a brand reduces the size or quantity of a product while keeping the price the same — or close to it. The box looks identical. The shelf tag barely moves. But you are getting less for your money.
It is legal. It is common. And it is almost impossible to detect without tracking unit prices over time.
Between 2022 and 2025, hundreds of everyday grocery products quietly shrank. Chips bags. Cereal boxes. Coffee cans. Paper towels. Toilet paper. The pattern was consistent: brands absorbed cost increases not by raising the sticker price — which consumers notice — but by reducing quantity, which most consumers do not.
The Federal Trade Commission flagged it. Consumer Reports documented it. Shoppers felt it in their grocery bills without being able to point to exactly why.
What Existing Tools Get Wrong
There are apps that help with grocery prices. Most of them solve a different problem.
Coupon apps and cash-back tools are built around deals. They show you what is on sale this week. That is useful — but a sale price is not the same as a fair price. A 10% off coupon on a product that shrank 15% is not a deal. It is a marketing move.
Crowd-sourced price trackers require you to scan receipts or enter prices manually. Most people do not do this consistently. And even when they do, the data reflects what the community submitted — not what you personally paid.
None of these tools answer the question that actually matters: compared to what I paid six months ago, am I paying more for this product today?
What CartSnitch Does Differently
CartSnitch connects to your existing store loyalty accounts — mPerks for Meijer, Kroger Plus for Kroger, Target Circle for Target. When you shop, your purchase history flows in automatically. No scanning. No manual entry. No behavior change.
From that data, CartSnitch tracks three things:
Your price history. What you actually paid for each item, over time. Not the store advertised price. Your price.
Unit prices. Price per ounce, price per count, price per unit — whatever is appropriate for the product. When the box shrinks and the price stays flat, the unit price goes up. CartSnitch catches this automatically.
Price comparison across your stores. If you shop at Kroger and Meijer, CartSnitch shows you what each item costs at each store, so you can make informed decisions about where to shop.
You do not have to do anything differently. Connect your loyalty accounts once, and CartSnitch works in the background.
Who This Is For
CartSnitch is built for anyone whose grocery bill has gone up — which is most people — and who wants to understand why.
It is for the shopper who has a feeling that something changed but cannot put a number on it. It is for the household that is spending $20 more per week at the grocery store and does not know if that is inflation, shrinkflation, or just buying different things.
It is not for couponers looking for their next deal. There are better tools for that. CartSnitch is for people who want to understand their actual spending, over time, with real data.
Where We Are
CartSnitch is launching public beta on April 24, 2026. Three stores at launch: Meijer, Kroger, and Target. More on the roadmap.
It is free. No subscription. No trial period. You connect your loyalty account, and CartSnitch starts tracking.
If you have been watching your grocery bill and wondering where the money is going, that is exactly what we built this for.
