About this app

CartSignal helps you find the best grocery prices before you leave the house.

Prices change store to store and week to week — CartSignal tracks real, crowdsourced prices reported by shoppers like you, so you can compare before you shop instead of guessing.

How it works
• Enter your ZIP code to see prices at grocery stores near you
• Scan a barcode or search by product name to find what you're looking for
• Compare regular, sale, and member/loyalty prices side by side
• See how fresh each price is, with a confidence rating based on recent submissions
• Sort by lowest price, nearest store, or most recently reported

Built by the community
Don't see a price, or see one that's out of date? Submit what you find at the store — every report helps keep prices accurate for everyone nearby. Can't find a product in our catalog? Request it and we'll add it.

Browse by category
Shop by department — produce, dairy, meat, pantry staples, and more — to compare prices across everything on your list, not just one item at a time.

CartSignal is in active beta. Pricing data is community-submitted and improves as more shoppers contribute — always confirm pricing at the store before purchasing. CartSignal is not affiliated with any retailer and makes no guarantees regarding price accuracy or completeness.
