Know Before You Go.
Compare Real Local Grocery Prices.

Simply enter your zip code or choose the pin to localize your zip to your current location, then either type a product name or scan a barcode to see pricing.

The homepage shows the most recent price changes submitted to CartSignal.

CartSignal can show you stores within 10, 20, or 30 miles of your location.  Simply enter your zip code or choose the pin to localize the zip to your current location, and choose your radius in the drop-down.

Add items to your grocery list, choose quantities, and see your prices update dynamically.  Store comparisons will take the same item prices or a similar item price if the original is not available at that store, and dynamically figure out which store could potentially save you more money. 

*This feature will improve as pricing data improves over time, and is only an estimate of potential savings!

Each product page will allow you to add the item to your Grocery List or see recent price trends with the provided graph.

Each product page will also show you a list of reported prices for stores in your local area, you can sort by Nearest stores, Lowest Price, or Freshest (most recent pricing data).
