draft Grocery prices have risen 25% since 2020, but tracking what you actually pay — and whether you're getting a fair deal — has been nearly impossible. Until now.

Why We Built CartSnitch: Your Grocery Bill Shouldn't Be a Mystery

You know the feeling. You're at the register, the total pops up, and it's... more than you expected. Again. You could swear that box of cereal was $3.49 last month. Was it? You can't remember. You can't prove it. And that's exactly how it's designed to work.

The numbers don't lie — your gut is right

According to the Bureau of Labor Statistics, grocery prices have risen 25% since January 2020. The USDA's food price outlook for 2026 projects another 2-4% increase this year alone. But those are averages. The reality at the shelf is messier:

  • Eggs surged over 70% in 2023, dropped, then climbed again in early 2026.
  • Snack foods have seen steady 8-12% annual increases — often masked by shrinking package sizes.
  • Store-brand products, once the reliable budget option, have seen price increases outpacing name brands in some categories.

The problem isn't just that prices go up. It's that you have no way to track your prices, at your stores, on the products you actually buy.

The shrinkflation problem nobody talks about

Here's something that won't show up in inflation statistics: your favorite ice cream went from 1.75 quarts to 1.5 quarts. Same price. Same shelf space. Same packaging design — just slightly shorter if you look closely.

This is shrinkflation, and it's everywhere:

  • Cereals have lost 1-3 oz per box across major brands since 2021
  • Toilet paper rolls have fewer sheets (some brands dropped from 1,000 to 900 sheets per mega roll)
  • Chip bags contain more air and less product — sometimes 2+ oz less than the same SKU two years ago
  • Detergent loads-per-bottle claims have quietly decreased while prices held steady or increased

Inflation numbers don't capture this. Your receipt doesn't show it. But your grocery budget feels it — an invisible 10-15% price increase that nobody is tracking.

What CartSnitch does

CartSnitch connects to your store loyalty accounts (starting with Meijer, with Kroger and Target coming soon) and builds a complete picture of your grocery spending:

  • Price history for every product you buy. See exactly how much that gallon of milk cost three months ago vs. today.
  • Store comparison. The same item at two stores 0.3 miles apart can differ by $1 or more. We show you where.
  • Shrinkflation alerts. When a product's package size decreases, we flag it — so you know you're paying more per ounce even if the sticker price didn't change.
  • Price drop notifications. Set a target price and we'll let you know when it hits.

No manual entry. No scanning barcodes. Just connect your loyalty account and we do the rest.

Why this matters

The average American household spends $270 per week on groceries (USDA, 2025). That's over $14,000 a year. Even small optimizations — switching stores for key items, timing purchases around price drops, catching shrinkflation before it eats your budget — can save hundreds annually.

But you can't optimize what you can't see. And right now, the data asymmetry is massive: retailers and brands have detailed analytics on every price change, promotion, and package adjustment. Consumers have... a fading memory of what they paid last time.

CartSnitch flips that equation. We give consumers the same price intelligence that retailers have always had.

What's next

We're launching first in Southeast Michigan with Meijer support. Kroger and Target follow within weeks. If you want to be among the first to track your grocery prices and catch shrinkflation in real time, sign up for early access.

Your grocery bill shouldn't be a mystery. Let's fix that.
